The reaction of bis(germavinylidene) [(Me3SiN=PPh2)(2)C=Ge -> Ge= C(PPh2=NSiMe3)(2)] (1) with CpMn(CO)(2)(THF) (Cp = eta(5)-C5H5) in THF afforded [(Me3SiN=PPh2)(2)C=Ge -> Mn(CO)(2)Cp] (2). Similar reaction of 1 with (cod)RhCl (cod = 1,5-cyclooctadiene) in THF gave [(Me3SiN=NPPh2)(2){(cod)Rh}C-GeCl] (3). The results suggested that reactive germavinylidene may exist in solution. The X-ray structures of 2 and 3 have been determined.
