Photolysis of a C6D6 solution of Cp‘W(CO)3GeMe2GeMe3 (1a, Cp‘ = Cp*, Cp* = η5-C5Me5; 1b, Cp‘ = CpEt, CpEt = η5-C5Me4Et) afforded a germyl(germylene)tungsten complex, Cp‘W(CO)2(GeMe2)(GeMe3) (2a, Cp‘ = Cp*; 2b, Cp‘ = CpEt), quantitatively. Crystal structure analysis of 2b revealed a significantly short tungsten−germylene bond (2.4590(16) A) compared to the tungsten−germyl bond (2.667(3) A) and planar geometry around the germanium atom of the germylene ligand (sum of the valence angles 357.8°), indicating sp2 hybridization of the germanium atom.
