Polarized absorption spectra of technetium(IV) and rhenium(IV) in trigonal single crystals of (C2H5NH3)2 [SnCl6] and (C2H5NH3)2[SnBr6] have been measured in the range of 8000 to 2800 Å at 298 and 77 °K. The crystal point group is D3d and the metal ions occupy sites of D3d-symmetry too. The observed excited levels arise from both π24d3 and π23d4 configurations; the different temperature and polarisation dependence of d → d intra-shell and π → d metal reduction transitions is discussed. Experimental values of the parameters Dq (cubic) and υ (trigonal) are reported. The nephelauxetic ratio β55 is evaluated from the 4A2g→2T2g intrasubshell transitions. The electron transfer spectra suggest the optical electronegativity xopt = 2.3 for Tc(IV) and xopt = 2.1 for Re(IV).

Single crystals of K1.10Zr2Se6, Rb0.86Zr2Se6 and Cs0.80Zr2Se6 were obtained by reacting powdered mixtures of A2Se (A = K, Rb, Cs), Zr and Se at 850 °C. K1.10Zr2Se6 and Rb0.86Zr2Se6 crystallize in space group Immm (Z = 2), with a = 3.746(3), b = 5.354(8), c = 21.929(3) Å and a = 3.756(1), b = 5.354(8), c = 22.81(1) Å , respectively. Cs0.80Zr2Se6 crystallizes in space group Cmc21 (Z = 2), with a = 3.747(1), b = 24.102(5), c = 5.332(2) Å. The compounds are characterized by complex anionic layers 2∞[Zr2Se6]x- with intercalated alkali cations. As in ZrSe3, the layers are built from columns of trigonal prisms 1∞[ZrSe3], connected by additional waist contacts, yielding an eightfold coordination for the Zr atoms. The mean Zr-Se bond lengths correspond to those found in the binary compound. The Se-Se bond lengths are significantly altered, however, indicating a reduction of the Se-Se bond order due to the electron transfer from the alkali metal.

Diffraction Diagram

A new type of synthetic industrial diamond formed by an explosive shock process has been recently developed by the Du Pont Company. This material consists of a mixture of two basically different forms, as shown in Figure 1: relatively flat and compact aggregates of acicular crystallites, and single crystals in the form of irregular polyhedra with straight edges.Figure 2 is a high magnification micrograph typical for the fibrous aggregates; it shows that they are composed of bundles of crystallites 0.05-0.3 μ long and 0.02 μ. wide. The selected area diffraction diagram (insert in Figure 2) consists of a weak polycrystalline ring pattern and a strong texture pattern with arc reflections. The latter results from crystals having preferred orientation, which shows that in a given particle most fibrils have a similar orientation.

Different Types

In polyethylene single crystals pairs of black and white lines spaced 700-3,000Å apart, parallel to the [100] and [010] directions, have been identified as microsector boundaries. A microsector is formed when the plane of chain folding changes over a small distance within a polymer crystal. In order for the different types of folds to accommodate at the boundary between the 2 fold domains, a staggering along the chain direction and a rotation of the chains in the plane of the boundary occurs. The black-white contrast from a microsector boundary can be explained in terms of these chain rotations. We demonstrate that microsectors can terminate within the crystal and interpret the observed terminal strain contrast in terms of a screw dislocation dipole model.
