Ramayan actor Dipika Chikhlia says she would like to play Kaikeyi, Sunil Lahiri'spick is Raavan

Actor Dipika Chikhlia, who was seen playing the role of Sita in Ramayan, was introduced to an unmatched popularity that has not faded even today. In an earlier interview, she had revealed how people in the villages would still refer to her as Sita and would even try touching her feet! However, given a choice today, Sita would not be the character she would like to play.

In a recent conversation, Dipika revealed she had evolved as an actor, and would rather be interested to play Kaikeyi, lord Ram's stepmother who insisted her husband Dashratha to send Ram, Lakshman and Sita to an exile for 14 years. Dipika added that playing a negative career was an entirely different experience and she was fond of playing roles that let her explore herself as an artist.

Actor Sunil Lahiri, who played Lakshman's character, said he'd still pick the same role, but if he had another choice, he would like to get into the shoes of Ravana as the character had many shades and would give an actor many varieties to perform.

As the nationwide lock-down began, Doordarshan started re-airing some of its most popular TV shows, Ramayan being the first one. On April 16, it became the world's most watched TV show, with 7.7 crore viewers.

UK-Africa Relations: Reflections on the Role of African Diplomacy in London

Invitation Only Research Event

13 January 2014 - 11:00am to 12:00pm

Chatham House, London

Event participants

HE Professor Kwaku Danso-Boafo, High Commissioner for Ghana to the United Kingdom
Chair: Alex Vines OBE, Research Director, Area Studies and International Law; Head, Africa Programme, Chatham House

Rapid economic growth and more widespread political stability have catalyzed increased international engagement with Africa in the past decade, as African states develop more significant roles in the global economy and political cooperation in geopolitics. Accompanying this is a shift in British engagement with African states from one with a development aid emphasis to one focused on trade and political cooperation.

HE Professor Kwaku Danso-Boafo will reflect on his time in London, developments in UK-Africa relations, the role of diplomatic engagements in informing and strengthening bilateral relations and the prospects for intergovernmental cooperation on African and global issues.

Attendance at this event is by invitation only.

India's fuel consumption dips 46 pc in April; expected to rebound in May

India's fuel consumption fell almost 46 per cent in April as all petroleum products, except LPG, saw massive demand erosion following the nationwide lockdown that halted economic activity and travel. The demand, which showed signs of pick up in the last 10 days of April after the government allowed resumption of economic activity beyond the urban municipal limit, is likely to rebound in second half of May as more areas are opened. India's fuel consumption fell 45.8 per cent to 9.929 million tonnes in April, down from 18.32 million tonnes fuel consumed in the same month a year back, according to official data released by the petroleum ministry. Fuel consumption during March, when travel restrictions began to be imposed to curb the spread of coronavirus, stood at 16.08 million tonnes. Petrol sales were down 60.43 per cent to 9,73,000 tonnes in April. The demand for the fuel had fallen 64 per cent in first half of the month, but there was some pick up in sales after reopening of some ...

Structure of the 4-hydroxy-tetrahydrodipicolinate synthase from the thermoacidophilic methanotroph Methylacidiphilum fumariolicum SolV and the phylogeny of the aminotransferase pathway

The enzyme 4-hydroxy-tetrahydrodipicolinate synthase (DapA) is involved in the production of lysine and precursor molecules for peptidoglycan synthesis. In a multistep reaction, DapA converts pyruvate and l-aspartate-4-semialdehyde to 4-hydroxy-2,3,4,5-tetrahydrodipicolinic acid. In many organisms, lysine binds allosterically to DapA, causing negative feedback, thus making the enzyme an important regulatory component of the pathway. Here, the 2.1 Å resolution crystal structure of DapA from the thermoacidophilic methanotroph Methylacidiphilum fumariolicum SolV is reported. The enzyme crystallized as a contaminant of a protein preparation from native biomass. Genome analysis reveals that M. fumariolicum SolV utilizes the recently discovered aminotransferase pathway for lysine biosynthesis. Phylogenetic analyses of the genes involved in this pathway shed new light on the distribution of this pathway across the three domains of life.

In the crystal structure of the title compound, [Sn(C42H26N6)(C7H5O2)2], the SnIV ion is located on a crystallographic inversion centre and is octa­hedrally coordinated with an N4O2 set. Four N atoms of the porphyrin ring form the equatorial plane while the axial positions are occupied by two O atoms from benzoate anions. The molecular packing of the title complex involves non-classical hydrogen bonds of the types C—H⋯O and C—H⋯N, leading to a three-dimensional network structure.

The ethyl­phenyl ring and the two phenyl rings subtend angles of 71.09 (7), 43.95 (5) and 36.53 (9)°, respectively, with the imidazole plane. An intra­molecular O—H⋯N hydrogen bond supports the mol­ecular conformation, and an inter­molecular C—H⋯O inter­action, originating from an ortho-phenyl H atom, stabilizes the packing arrangement. In addition, a weak C—H⋯π inter­action, also involving an ortho-phenyl H atom, is observed.

The title salt, (PMIM)2[Ni(P2S8)2] (PMIM = 3-methyl-1-propyl-1H-imidazol-3-ium, C7H13N2+), consists of a nickel–thio­phosphate anion charge-balanced by a pair of crystallographically independent PMIM cations. It crystallizes in the monoclinic space group P21/n. The structure exhibits the known [Ni(P2S8)2]2− anion with two unique imidazolium cations in the asymmetric unit. Whereas one PMIM cation is well ordered, the other is disordered over two orientations with refined occupancies of 0.798 (2) and 0.202 (2). The salt was prepared directly from the elements in the ionic liquid [PMIM]CF3SO3. Whereas one of the PMIM cations is well behaved (it does not exhibit disorder even in the propyl side chain), the other is found in two overlapping positions. The refined occupancies for the two orientations are roughly 80:20. Here, too, there appears to be little disorder in the propyl arm.

Crystal structure, Hirshfeld surface analysis and inter­action energy and DFT studies of 5,5-diphenyl-1,3-bis­(prop-2-yn-1-yl)imidazolidine-2,4-dione

The title compound, C21H16N2O2, consists of an imidazolidine unit linked to two phenyl rings and two prop-2-yn-1-yl moieties. The imidazolidine ring is oriented at dihedral angles of 79.10 (5) and 82.61 (5)° with respect to the phenyl rings, while the dihedral angle between the two phenyl rings is 62.06 (5)°. In the crystal, inter­molecular C—HProp⋯OImdzln (Prop = prop-2-yn-1-yl and Imdzln = imidazolidine) hydrogen bonds link the mol­ecules into infinite chains along the b-axis direction. Two weak C—HPhen⋯π inter­actions are also observed. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H⋯H (43.3%), H⋯C/C⋯H (37.8%) and H⋯O/O⋯H (18.0%) inter­actions. Hydrogen bonding and van der Waals inter­actions are the dominant inter­actions in the crystal packing. Computational chemistry indicates that the C—HProp⋯OImdzln hydrogen-bond energy in the crystal is −40.7 kJ mol−1. Density functional theory (DFT) optimized structures at the B3LYP/6–311G(d,p) level are compared with the experimentally determined mol­ecular structure in the solid state. The HOMO–LUMO behaviour was elucidated to determine the energy gap.

The title compounds, 8-amino-6-methyl-3,4-diphenyl-1H-isochromen-1-one, C22H17NO2, (I), and 8-amino-3,4-diethyl-6-methyl-1H-isochromen-1-one, C14H17NO2, (II), are new isocoumarin derivatives in which the isochromene ring systems are planar. Compound II crystallizes with two independent mol­ecules (A and B) in the asymmetric unit. In I, the two phenyl rings are inclined to each other by 56.41 (7)° and to the mean plane of the 1H-isochromene ring system by 67.64 (6) and 44.92 (6)°. In both compounds, there is an intra­molecular N—H⋯O hydrogen bond present forming an S(6) ring motif. In the crystal of I, mol­ecules are linked by N—H⋯π inter­actions, forming chains along the b-axis direction. A C—H⋯π inter­action links the chains to form layers parallel to (100). The layers are then linked by a second C—H⋯π inter­action, forming a three-dimensional structure. In the crystal of II, the two independent mol­ecules (A and B) are linked by N—H⋯O hydrogen bonds, forming –A–B–A–B– chains along the [101] direction. The chains are linked into ribbons by C—H⋯π inter­actions involving inversion-related A mol­ecules. The latter are linked by offset π–π inter­actions [inter­centroid distances vary from 3.506 (1) to 3.870 (2) Å], forming a three-dimensional structure.

Bis[2-(4,5-diphenyl-1H-imidazol-2-yl)-4-nitrophenolato]copper(II) dihydrate: crystal structure and Hirshfeld surface analysis

The crystal and mol­ecular structures of the title CuII complex, isolated as a dihydrate, [Cu(C21H14N3O3)2]·2H2O, reveals a highly distorted coordination geometry inter­mediate between square-planar and tetra­hedral defined by an N2O2 donor set derived from two mono-anionic bidentate ligands. Furthermore, each six-membered chelate ring adopts an envelope conformation with the Cu atom being the flap. In the crystal, imidazolyl-amine-N—H⋯O(water), water-O—H⋯O(coordinated, nitro and water), phenyl-C—H⋯O(nitro) and π(imidazol­yl)–π(nitro­benzene) [inter-centroid distances = 3.7452 (14) and 3.6647 (13) Å] contacts link the components into a supra­molecular layer lying parallel to (101). The connections between layers forming a three-dimensional architecture are of the types nitro­benzene-C—H⋯O(nitro) and phenyl-C—H⋯π(phen­yl). The distorted coordination geometry for the CuII atom is highlighted in an analysis of the Hirshfeld surface calculated for the metal centre alone. The significance of the inter­molecular contacts is also revealed in a study of the calculated Hirshfeld surfaces; the dominant contacts in the crystal are H⋯H (41.0%), O⋯H/H⋯O (27.1%) and C⋯H/H⋯C (19.6%).

Crystal structure of pyridinium tetra­iso­thio­cyanato­dipyridine­chromium(III) pyridine monosolvate

In the crystal structure of the title compound, (C5H6N)[Cr(NCS)4(C5H5N)2]·C5H5N, the CrIII ions are octa­hedrally coordinated by four N-bonding thio­cyanate anions and two pyridine ligands into discrete negatively charged complexes, with the CrIII ion, as well as the two pyridine ligands, located on crystallographic mirror planes. The mean planes of the two pyridine ligands are rotated with respect to each other by 90°. Charge balance is achieved by one protonated pyridine mol­ecule that is hydrogen bonded to one additional pyridine solvent mol­ecule, with both located on crystallographic mirror planes and again rotated by exactly 90°. The pyridinium H atom was refined as disordered between both pyridine N atoms in a 70:30 ratio, leading to a linear N—H⋯N hydrogen bond. In the crystal, discrete complexes are linked by weak C—H⋯S hydrogen bonds into chains that are connected by additional C—H⋯S hydrogen bonding via the pyridinium cations and solvent mol­ecules into layers and finally into a three-dimensional network.
