Substitution of a platinum (II) complex without retention of stereochemistry; direct evidence for pseudorotation of a five-co-ordinate platinum (II) cationic complex containing chelating phosphine ligands

Abstract

Ring closure of trans-[Pt(PNH₂)(PNH₂)Cl]⁺(2)[PNH₂=(O-aminophenyl)diphenylphosphine; PNH₂ denotes monodentate co-ordination through the phosphorus] proceeds without retention of stereochemistry; this is the first direct evidence for pseudorotation of five-co-ordinate platinum (II) complex.
