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.

The symmetries of the observed Raman lines in the 4000–30 cm−1 region in different orientations of a single crystal of Ba(NO2)2•H2O have been determined and the spectra have been analysed in terms of the phonons originating from the internal modes of the NO2− and H2O groups and the external lattice modes. The longitudinal-optical and transverse-optical (LO–TO) splittings arising from the Coulomb forces in the crystal arc reported for the first time.
