Crystals of K2TeBr6 are monoclinic, space group [Formula: see text] with a = 7.521, b = 7.574, and c = 10.730 Å; β = 89° 40′. Atomic positions have been found by three dimensional X-ray diffraction analysis (least squares R = 0.12). The crystals possess a K2PtCl6 structure which is distorted to allow a more efficient packing of the comparatively large anions than is possible with the undistorted cubic form. The stereochemistry of the octahedral TeBr6− ion (Te—Br = 2.71 Å) is discussed.

Microscopy Techniques

The development of modern electron microscopy techniques to visualize the hydrated structures of biological macromolecules has stimulated many new studies, especially with viruses and virus-macromolecule complexes that are too large to study with current x-ray crystallographic methods, Cryo-electron microscopy (cryoEM) in conjunction with three-dimensional reconstruction procedures is capable of revealing both external and internal features of these structures.

A mixed-ligand orotato (HOr) complex of Cu(II) with 2,2’-bipyridine (bipy) was synthesized and characterized by elemental analysis, magnetic susceptibility, UV-vis and FT-IR spectroscopy, TG / DTA techniques and X-ray diffraction analysis. X-Ray diffraction analysis has shown that the squarepyramidal five-coordinate copper atom is chelated by the deprotonated N3 pyrimidine atom and the carboxylate oxygen atom of the bidentate orotato dianion, and to the two nitrogen atoms of the 2,2’- bipyridine molecule. A water molecule is attached above the N3O plane. Thermal analyses showed that the title compound decomposes in two steps over the range 20 - 1000 °C on heating in a static air atmosphere. Intermolecular hydrogen-bonds and π-ring interactions lead to the formation of a three-dimensional network.

Single-crystal X-ray diffraction analysis has been performed on dysprosium ultraphosphate, DyP5O14, prepared by the flux method. The atomic arrangement is built up of layers of independent P8O24 rings perpendicular to the b axis interconnected by PO4 groups to form a three-dimensional network of PO4 tetrahedra. Two sites are located on the twofold axis for the Dy atoms, which have almost regular dodecahedral coordination.
