Binary chalcogen halogen EX4 species represent intriguing systems in terms of chemical bonding theories, such as hypervalency and stereoactivity of lone electron pairs. Instead of a simple molecular EX4 structure, selenium tetrachloride forms an ionic pair, Cl3Se+Cl−, that assembles into a tetrameric (SeCl4)4 structure, namely, tetra-μ3-chlorido-dodecachloridotetraselenium. This article describes the charge–density analysis of the tetrameric molecule of β-SeCl4 based on the aspherical model obtained from Hirshfeld Atom Refinement of the tetrameric molecule and of an explicit cluster of 15 tetramers that simulates the crystal packing. Deformation density, electron localization function (ELF) and Quantum Theory of Atoms in Molecules (QTAIM) were used to evaluate the bonding situation, the electron-density distribution around the Se atom and the interaction energy of the tetramer.

The title compound, C14H8Cl2F3NO, was synthesized by the condensation between trifluoromethylaniline and dichlorosalicylaldehyde by nucleophilic addition, forming a hemiaminal, followed by a dehydration to generate an imine. The compound crystallizes in an orthorhombic Pbca (Z = 8) space group with a dihedral angle of 44.70 (5)° between the two aromatic rings. In the crystal, the molecules pack together to form a zigzag pattern along the c axis.

April 17, 2015 It was more than just a handshake at the Summit of the Americas last week as President Barack Obama greeted Cuba’s President Raul Castro. It has been widely described as the beginnings of a thaw in US-Latin American relations. It’s been welcomed in some quarters as a mark of progress in American foreign policy while condemned by others as a capitulation to a long-standing communist enemy.

This week, Basic Black looks at the changes in US-Latin American relations and what impact this could have on Latinos living in the United States, immigration reform and economic development for Latin America. Panelists:
