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·H2Ge-GeH2·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 σ-bonds within the H2Ge-GeH2 arrays and dative Ge-C interactions between the digermene and the carbon-based Lewis bases.

The synthesis of a series of N-heterocyclic carbene (NHC) complexes involving zinc, cadmium, and the heavy Group 14 elements germanium, tin, and lead is reported. The direct reaction between the bulky carbene IPr (IPr≤(HCNDipp)2C:, Dipp≤2,6-iPr2C6H3) and the Group 14 halide reagents GeCl4 and SnCl4 afforded the 1:1 complexes IPr·ECl4 (E≤Ge and Sn) in high yield; similarly, ZnI2 interacted with IPr in THF to give the THF-bound complex IPr·ZnI2·THF. CdCl2 underwent divergent chemistry with IPr and the major product isolated was the imidazolium salt [IPrH] [IPr·CdCl3], which could be converted into IPr·CdCl2·THF upon treatment with Tl[OTf]. In addition, the stable PbII amide adduct, IPr·PbBr(NHDipp), was prepared. Each of the new carbene-element halide adducts was treated with the hydride sources Li[BH4] and Li[HBEt3] in order to potentially access new element hydride adducts and/or clusters. In most instances scission of the element-carbene bonds transpired, except in the case of IPr·ZnI2·THF, which reacted with two equivalents of Li[BH4] to yield the thermally stable bis(borohydride) zinc complex IPr·Zn(BH4)2.

To branch or not to branch: A mild stepwise route to various linear and branched (GeCl2)x oligogermylenes supported by Lewis bases is reported, including the carbene-bound Ge4 complex NHC×GeCl2Ge(GeCl3)2 (see picture). Dipp=2,6-iPr2C6H3, NHC=N-heterocyclic carbene. Copyright
