The elusive parent inorganic ethylene H2GeGeH2 has been isolated in the form of a stable complex for the first time via donor-acceptor coordination with suitable Lewis base/acid combinations (LB center dot H2Ge-GeH2 center dot LA; LB = N-heterocyclic carbene or N-heterocyclic olefin; LA = W(CO)(5)). The nature of the bonding in these species was investigated by density functional theory calculations and revealed the presence of polarized Ge-Ge covalent sigma-bonds within the H2Ge-GeH2 arrays and dative Ge-C interactions between the digermene and the carbon-based Lewis bases.
