A novel type of diazadiene co-ordination behaviour. X-Ray structure of a rhodium complex with bridging azomethine groups

Abstract

The single crystal X-ray diffraction study of the complex with seemingly simple stoicheiometry (dad) RhCl (dad = Bu^tNCH–CHNBu^t), obtained from the room temperature reaction of [(C₂H₄)₂RhCl]₂ with dad, indicates a cleavage of the central C–C bond in one out of two dad ligands to result in two bridging azomethine groups in [(dad)ClRh(µ-HCN–Bu^t)₂Rh(µ′-Cl)]₂(4).
