Lattice Constants

Pb2P2Se6 crystallizes in the monoclinic system, space group Pn (No. 13) with the lattice constantsa = 974.2 (4) pm. b = 766.2 (3) pm. c = 689.8 (3) pm, β=91.44(5)°.The title compound is isotypic to the homologous Pb2P2S6. In the structure there are discrete P2Se4-6 anions.Far infrared, infrared and Raman spectra of this compound have been recorded. The observed frequencies are assigned on the basis of P2Se4-6 units with C2h symmetry in the crystal. DTA-data have been determined and interpreted.

Far infrared, infrared and Raman spectra of tin hexathiohypodiphosphate Sn2P2S6 (mono­clinic modification II) have been recorded. The observed frequencies are assigned on the basis of P2S64-units with C2h symmetry in the crystal. The assignment is supported by the correlation D3d (dissolved P2S64- ion) → C2h. DTA-data have been determined and interpreted.

Far Infrared Spectra

The infrared and Raman spectra of [Et3PcuI]4 and [Et3AsCuI]4 have been measured, and bands have been assigned to vibrations of the ligand and of the Td Cu4I4 core. The far-infrared spectra show two strong T2 v(CuI) bands at about 90 and 140 cm-1, the higher frequency member of which has a Raman counterpart which shows possible longitudinal-transverse splitting. The Raman spectra also show an intense band at about 50 cm-1. Similar features have been observed in the low-frequency vibrational spectra of [Et2S]3 [CuI]4, [C5H5NcuI]4, [C5H11NAgI]4, [Et3PAgBr]4 and [Et3PagCl]4, although the last two compounds gave only a single broad band in the v(MX) region.
