摘要：

The first dinuclear complex bridged by a substituent-free gallium atom, Cp*Fe(dppe)(mu-Ga)Fe(CO)(4) (1; CP* = eta-C5Me5, dppe = Ph2PCH2CH2PPh2), was synthesized by the reaction of Cp*Fe(dppe)GaCl2 with K-2[Fe(CO)(4)]. A crystal structure analysis of complex 1 revealed that the geometry around the gallium atom is essentially linear and the Fe-Ga bonds are significantly shorter than that of usual single bonds. These structural features indicate that the Fe-Ga bonds bear significantly unsaturated character.
