Syntheses and room-temperature single-crystal X-ray structure determinations are recorded for the title compounds, [bpyH]+[(bpy)BiX4]-, X = Cl, Br, the chloride being obtained in a second acetonitrile- sesquisolvated form. [bpyH]+[(bpy)BiX4]-, X = Cl, Br, are isomorphous, monoclinic C2/c, a ≈ 15·3, b ≈ 9·6, c ≈ 16·8 Å, β 109°, Z = 4, conventional R on |F| being 0·056, 0·059 for No 1456, 769 independent ‘observed’ (I > 3σ(I)) reflections respectively. [bpyH] [(bpy)BiCl4].1½MeCN is monoclinic, P21/m, a 9·572(2), b 34·521(8) c 8·218(2) Å, β 102·13(2)°, Z = 4, R 0·043 for No 2635. All anionic species are mononuclear, the bismuth being quasi-octahedral. Bands in the far-infrared and Raman spectra due to the vibrations of the N2BiCl4 core in [(bpy)BiCl4]- are assigned, and their relationship to the vibrations of [BiCl6]3- is discussed.

Room-temperature single-crystal X-ray studies are recorded for some dimethyl sulfoxide (dmso) solvates of bismuth(III) bromide and iodide. Colourless BiBr3.3dmso is triclinic, P-1, a 8·467(4), b 9·109(4), c 13·901(4) Å, α 76·34(4), β 76·95(4), γ 64·56(4)°, Z = 2; conventional R on |F| was 0·050 for No 2306 independent ‘observed’ (I > 3σ(I)) reflections. The complex is mononuclear with a quasi-octahedral fac-bismuth environment, [(dmso-O)3BiBr3], isomorphous with the previously determined chloride. Orange BiI3-2dmso is triclinic, P-1, a 12·558(2), b 8·962(2), c 8·342(1) Å, α 61·85(1), β 78·27(1), γ 76·89(2)°, Z = 2 f.u., R 0·048 for No 1953. The complex is binuclear, a pair of iodide atoms bridging the two bismuth atoms, [(dmso-O)2I2Bi(µ-I)2BiI2(O-dmso)2]; the two O-dmso ligands about each six-coordinate bismuth lie trans. Red BiI3.2 ⅔ dmso is triclinic, P-1, a 16·435(6), b 14·926(2), c 12·396(3) Å, α 74·89(2), β 73·24(2), γ 79·18(2)°, Z = 6, R 0·059 for No 5858. The complex is [Bi(O-dmso)8] [Bi2I9], the eight-coordinate metal environment of the cation being, unusually, dodecahedral; in the anion a pair of quasi-octahedral six-coordinate bismuth atoms are bridged by three iodides, [I3Bi(µ-I)3BiI3]3-. Bands in the far-infrared and Raman spectra due to the v(BiX) modes are assigned and discussed in relation to the structures of the complexes. The assignment of the v(BiO) modes is discussed.

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.
