Abstract

The nucleophilicity of the bridging atom of the selenium complex (μ-Se)[(η5-C5H5)Fe(CO)2]2 (1) has been demonstrated by addition of the complex cation [(η5-C5H5)Fe(CO)2]+: Reaction of 1 with the ionic complex [(η5-C5H5)Fe(CO)2-(THF)][BF4] cleanly yields the ionic trinuclear complex [(μ3-Se)(η5-C5H5)-Fe(CO)23][BF4] (3). This addition reaction converts the bridging selenium atom from a bent FeSeFe structure into a flattened Fe3Se pyramid (X-ray diffraction studies), without significant changes in the iron-selenium bond lengths (244.9(<1) pm and 242.7(1)/243.3(1)/244.8(1) pm, respectively). These bonds are considered to be single bonds in accord with the EAN rule.
