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.

AbstractTransparent colorless crystals of NaA5[C6N9]2 · 4 H2O (A = Rb, Cs) were obtained by blending aqueous solutions of Na3[C6N9] and RbF or CsF, respectively, and subsequent evaporation of the water under ambient conditions. Both compounds crystallize in the space group P21/m (no. 11) with the cell parameters a = 815.56(16), b = 1637.7(4) and c = 1036.4(3) pm, and β = 110.738(12)° for NaRb5[C6N9]2 · 4 H2O and a = 843.32(6), b = 1708.47(11) and c = 1052.42(7) pm, and β = 112.034(2)° for NaCs5[C6N9]2 · 4 H2O, respectively. Raman spectra of the title compounds complement our results.

Tl2P2S6 crystallizes in the orthorhombic system, space group Immm, Z = 2 with the lattice constantsa = 793.2(4) pm, b = 689.2(4) pm, c = 901.9(5) pm.In the structure there are discrete P2S62- -anions. The P2S62- -ion was found to be a hexa-thiometadiphosphate group where the two P atoms are linked by two S bridges.Far infrared, infrared and Raman spectra of this compound have been recorded. The observed frequencies are assigned on the basis of P2S62- units with D2h symmetry in analogy to the isoelectronic Al2Cl6

Single crystals of Ca15(CBN)6(C2)2F2 were obtained by the reaction of graphite, hexagonal BN and CaF2 with an excess of distilled Ca metal in silica-jacketed Ta ampoules at 1300 K. The title compound is transparent red and crystallizes isopointal to Ca15(CBN)6(C2)2O adopting the cubic space group Ia 3̄d (no. 230, Z = 8) with the cell parameter a = 1653.6(4) pm. Its vibrational spectra are compared with IR and Raman data of similar compounds from the literature and with the newly measured Raman spectra of Ca5(BC2)(C2)Cl3 and Ca9(BC2)2Cl8.
