The absorption spectra of [Rh(SnCl3)4Cl2]3- and [Pt(SnCl3)5]3- are cha
racterized by a similar band pattern. It is suggested that the absorpt
ion spectra are dominated by bands which are assigned to intraligand t
ransitions. While solid (NBu4)3[Pt(SnCl3)5] shows a low-temperature em
ission the rhodium complex is not luminescent. Both complex anions are
light sensitive in acetonitrile solution. They undergo an efficient p
hotosubstitution of the trichlorostannyl ligand.
