The series of cis/trans-trifluoromethylselenato complexes [Pt(SeCF3)2 - xClx(PPh3)2] (x = 0, 1) was identified by NMR spectroscopic methods. While in acetonitrile solution spectra are dominated by the resonances of the cis derivatives, those of pure cis-[Pt(SeCF3)2(PPh3)2] indicate cis-trans-isomerisation in CH2Cl2 solution. In contrast, exchange reactions of cis-[PtCl2(PPh3)2] and [NMe4]TeCF3 only gave evidence for cis isomers. Molecular structures of cis- and trans-[Pt(SeCF3)2(PPh3)2] and cis-[Pt(TeCF3)2(PPh3)2] are discussed in comparison with related compounds.
