Syntheses of complexes containing the novel 1,2,3-azadiphosphole and 1,2,5-azadiphosphole ring systems: crystal and molecular structure of [Ir(η5-C5Me5)(η4-(ButCPNButPCBut)]

Abstract
The first examples of complexes containing the novel 1,2,5-azadiphosphole and 1,2,3-azadiphosphole ring systems are presented, together with the molecular structure of [Ir(η5-C5Me5)(η4-(Bu tCPNButPCBut)] as established by a single crystal X-ray diffraction study.
