Dynamic behaviour of the complex [Ni{PhC(S)NP(O)(OPri)2-O,S}2-{PhC(S)NHP(O)(OPri)2-O}2] in deuterotrichloromethane

Abstract

The title complex has been studied by 1H and 31P NMR spectroscopy and found to undergo reversible dissociation of its neutral ligands and interconversion of its neutral and anionic ligands; the kinetic parameters of these processes and the crystal structure of the complex were determined; a new ligand exchange mechanism with unusual high spin–low spin transition during the ligand dissociation was suggested.
