rat The modulated low-temperature structure of malayaite, CaSnOSiO4 By scripts.iucr.org Published On :: 2020-04-16 The crystal structure of the mineral malayaite has been studied by single-crystal X-ray diffraction at a temperature of 20 K and by calculation of its phonon dispersion using density functional perturbation theory. The X-ray diffraction data show first-order satellite diffraction maxima at positions q = 0.2606 (8)b*, that are absent at room temperature. The computed phonon dispersion indicates unstable modes associated with dynamic displacements of the Ca atoms. The largest-frequency modulus of these phonon instabilities is located close to a wavevector of q = 0.3b*. These results indicate that the malayaite crystal structure is incommensurately modulated by static displacement of the Ca atoms at low temperatures, caused by the softening of an optic phonon with Bg symmetry.

The structural modulation is attributed to a soft optic phonon, dominated by motion of the Ca atoms. Full Article text
rat catena-Poly[[[aquacopper(II)]-μ-(biphenyl-2,2'-dicarboxylato)-μ-[N,N'-bis(pyridin-4-yl)urea]] 1.25-hydrate] By scripts.iucr.org Published On :: 2020-05-05 In the title compound, {[Cu(C14H8O4)(C11H10N4O)(H2O)]·1.25H2O}n, the CuII cations are coordinated in a square-pyramidal fashion by trans carboxylate O-atom donors from two diphenate (dip) ligands, trans pyridyl N-atom donors from two bis(4-pyridyl)urea (bpu) ligands, and a ligated water molecule in the apical position. [Cu(H2O)(dip)(bpu)]n coordination polymer layer motifs are oriented parallel to (overline{1}02). These layer motifs display a standard (4,4) rectangular grid topology and stack in an AAA pattern along the a-axis direction to form the full three-dimensional crystal structure of the title compound, mediated by N—H...O and O—H...O hydrogen bonding patterns involving the water molecules of crystallization.
