Slip to π Ru: structural distortions due to metal-iminoxolene π bonding†
Abstract
Both pseudo-octahedral and pseudo-square pyramidal bis-iminoxolene complexes trans-(Diso)2RuCl2 and trans-(Diso)2Ru(PPh3) are structurally distorted, with the ruthenium atom slipping off the twofold axis of the idealized coordination polyhedra. These distortions take place because they allow or enhance π interactions between ruthenium and the iminoxolene π orbitals.
