Slip to π Ru: structural distortions due to metal-iminoxolene π bonding.
Patricia Rose H AysonSeth N BrownPublished in: Chemical communications (Cambridge, England) (2023)
Both pseudo-octahedral and pseudo-square pyramidal bis-iminoxolene complexes trans -(Diso) 2 RuCl 2 and trans -(Diso) 2 Ru(PPh 3 ) 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.
