complexes of the type [Mη3-[graphic omitted]}(CO)(η-C5H5)L](L = CO, CNBut, CNC6H11, or PPh3). The complex where L = CNBut and R = Me is structurally identified by single-crystal X-ray diffraction. Crystals are monoclinic, space group P21/a with four molecules in a unit cell of dimensions a= 9.3013(15), b= 22.161(6), c= 9.353(3)Å, and β= 102.76(2)°. The mode of formation of this type of complex is discussed
