Going straight : Thermolysis of the germylidyne complexes trans ‐[Cl(depe) 2 MGe(η 1 ‐Cp*)] (M=Mo, W; depe=Et 2 PCH 2 CH 2 PEt 2 , Cp*=C 5 Me 5 ) leads upon cleavage of the GeCp* bond to 1 , the first compounds in which a Ge 2 unit is trapped between two transition‐metal centers by triple bonds. Quantum chemical analyses suggest a weak conjugation of the M−Ge triple bonds in the linear chain MGeGeM.
