Perfect complementarity in the fitting of two homochiral heterodonor ligands around a nickel(II) centre: an 'intramolecular embrace'

摘要

The homochiral form of the complex [('P,N')(2)Ni](2+) ('P,N' is a phosphino-heteroatom bidentate ligand) has been found to be more stable than its heterochiral analogue due to a 'fitting' of the two 'P,N' ligands about the Ni that is reminiscent of an 'intramolecular embrace'. [References: 22]
