Tentative Assignment

The infrared spectrum in the range 3000–50 cm−1 and the Raman spectrum of solutions of dithiophosgene have been obtained. There are no coincidences in the infrared and Raman spectra, and the only structure consistent with this and approximately tetrahedral carbon valencies is[Formula: see text]that is tetrachloro-1,3-dithietane, in which the ring is planar or nearly planar. A tentative assignment of the observed bands is given on the basis of D2h symmetry.

Abstract Infrared and Raman spectra of the metal cluster compound [Nb6F12]F3 (cubic Im3̄m; Z = 2) are reported. The three intense m odes observed in the Raman spectrum at 215. 267, and 337 cm-1 and a weak mode observed in the infrared spectrum at 287 cm-1 are assigned to the T2g, Eg, A1g, and T1u vibrational modes of the Nb6 octahedra. The assignment is supported by normal coordinate analysis and Raman measurements at 47 kbar. The valence force constants are f(Nb-Fi) = 2.04, f(Nb-Fa-a) = 1.30 and f(Nb-Nb) = 0.97 N cm-1 metal-to-metal interaction in the cluster.

The ir spectra of (CH3)3SiCo(CO)4 in the gaseous (4000–250 cm−1) and solid (4000–33 cm−1) phases have been recorded. The Raman spectrum has also been recorded for the solid state. To aid in the assignment, the ir and Raman spectra were recorded of solid (CH3)3SiH. The vibrational assignment for most of the 60 normal modes has been given on the basis of the fundamental vibrations of the –Si(CH3)3 and –Co(CO)4 moities. The static field was sufficiently strong to split the degenerate modes but the correlation field was so weak that no definite splitting of the symmetric modes was detected.

Vibration Frequencies

The infrared spectrum of liquid and dissolved tetrabromoethylene has been investigated from 3µ–36µ. The Raman spectrum has been obtained photographically in the liquid state and photoelectrically in solution and depolarizations measured. All of the fundamentals were observed except v4, v7, v10, and v12. The last two vibration frequencies are estimated by calculations from two different potential functions.

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.
