Germanium / Transition metal complexes / Inidene compounds [Cp'(C0)2Mn=GeI=Mn(CO)2Cp']-, the First Germanium-"Inidene" Complex\* GeI, reacts with Na[(Cp'(CO),Mn),H] to form the inidenetype compound [Cp'(CO),Mn=GeI-Mn(CO)2Cp']-(1). The anion 1 contains Ge( 0) in a trigonal-planar coordination, embedded between two Cp'(CO),Mn groups and an iodo ligand. The intrinsic stability of the cumulene [Cp'(CO),Mn= Ge=Mn(CO),Cp'] is still apparent in the structure of 1: The Ge-Mn bonds are short (229 pm) while the Ge-I distance is rather long (284 pm). The inidene-type anion 1 can only be obtained from the above-mentioned reaction if the reaction is quenched by addition of unpolar solvents, thus eliminating starting materials and coproducts. Direct workup of the reaction mixture instead leads to [Cp'(CO)2MnGe13]-(2) as the only isolated product. The transformation of 1 into 2, which contains Ge in the formal oxidation state +2, necessarily implies redox processes, which are well documented in inidene chemistry.
