double bond react with the chloro-bridged complexes (Cp*)(Cl)M(µ-Cl)2M(Cp*)(Cl) with decarboxylation or loss of a benzoyl group to give the unexpected ligand-bridged dinuclear complexes 2 and 4, which were characterized by X-ray diffraction. In the iridium complex 2 an oxazolone derivative forms a C,O-N,N′-coordinated bridge, whereas in the rhodium complex 4 a chlorine atom and an amide group bridge
由 C=C 双键桥接的马尿酸二聚体与氯桥连配合物 (Cp*)(Cl)M(µ-Cl)2M(Cp*)(Cl) 反应,脱羧或失去苯甲酰基,得到意外的配体桥连双核复合物 2 和 4,通过 X 射线衍射表征。在铱络合物 2 中,恶唑酮衍生物形成 C,ON,N' 配位桥,而在铑络合物 4 中,氯原子和酰胺基团桥接两个金属原子。
