Formation and Structure of fac-[Mo(CO)3(C2H2[N(CH2Bu)]2Ge)3]: The First Structurally Characterized Group 6 Transition Metal Complex of an Unsaturated Diaminogermylene

The title compound was obtained from the cyclic diaminogermylene C2H2[N(CH2Bu 2Ge and cis-[Mo(CO)4(NCEt)2] and its crystal structure determined revealing structural changes in the coordinated ligand indicative of strong (PI)-acceptor properties.
