A short W−Ge triple bond and a η 1 ‐bound Cp* substituent are characteristic of the germylyne complexes 2 ⋅toluene that are obtained from the reaction of 1 with the germylene complexes [Cp*GeX] (W−Ge 2.302(1) Å for X=Cl). Density functional calculations show that there are significant electronic differences between germylyne and carbyne ligands. X=Cl, Br, I; PP=Ph 2 PCH 2 CH 2 PPh 2 ; Cp*=C 5 Me 5 .
