Abstract
The absorption spectra and photochemistry of trichlorostannyl complexes [M(SnCl3)6]4−, [M(SnCl3)5Cl]4− and [M(SnCl3)5AN]3− (M = Ru, Os; AN = acetonitrile) in acetonitrile were investigated. In view of the similarity of all absorption spectra it is suggested that the lowest energy transitions are largely of the intraligand type.

Abstract
The absorption spectra and photochemistry of trichlorostannyl complexes [M(SnCl3)6]4−, [M(SnCl3)5Cl]4− and [M(SnCl3)5AN]3− (M = Ru, Os; AN = acetonitrile) in acetonitrile were investigated. In view of the similarity of all absorption spectra it is suggested that the lowest energy transitions are largely of the intraligand type. The photolysis of these complexes in acetonitrile leads to substitutions of SnCl3− or in the case of [Ru(SnCl3)6]4− to a ligand fragmentation as primary photoreactions. Owing to secondary processes [M(snCl3)4(AN)2]2− is the terminal product of all the photoreactions. It is assumed that the photoreactions are initiated by intraligand excitation.
