EtCN) towards diethylamine has been investigated. The processes are chemo- (substitution versus addition) and stereo-selective in dependence of the stereochemistry of the precursor. The structures of [SP4-4]-[PtCl(CONEt 2 )(NHEt 2 )(PPh 3 )], [SP4-4]- 1 , trans -[PtCl 2 (NHEt 2 )(PPh 3 )], trans - 2 , and cis -[PtCl 2 (E-)HN C(NEt 2 )Me}(PPh 3 )], cis - 3a , are reported.
