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

The title complex has been studied by H-1 and P-31 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.
