The single-crystal polarised electronic absorption spectra of (X = Cl, Br or I) at room temperature and 5 K are reported in the range 10 000-40 000 cm-1.The spectra have been interpreted using the observed polarisation and vibrational fine-structure data in conjunction with a parameterised ligand-field model.The single-crystal structure of has been determined by X-ray crystallography.The compound crystallises in the tetragonal space group P4/n, a = b = 12.774(3), c = 8.008(3) Angstroem, Z = 2.The (1-) ion has 4mm (C4ν) symmetry with Os-N 1.583(15), Os-Br 2.457(1) Angstroem, N-Os-Br 10 4.29(3) deg.The (1+) cation has crystallographic 4 (S4) symmetry with As-C 1.891(8) Angstroem, C-As-C 105.12(48) and 116.69(25) deg.
