“…Group 14 hydrides, such as R 3 SiH, R 3 GeH, and R 3 SnH, are of great importance due to their industrial applications, synthetic chemistry, and the interesting nature of the chemical bonding. − Subvalent germanium and tin hydrides show a high reactivity and attracted considerable attention after the preparation of divalent tin(II)hydride (Ar·SnH) 2 in 2000 . Several germanium(II) hydrides featuring a central GeH 2 moiety flanked by electron-donating, electron-accepting, or both groups have been prepared based on kinetic or thermodynamic stabilization. − In principle, these species representing chemical analogues to the well-known carbenes provide considerable insights into the nature of the chemical structure and bonding in subvalent group 14 compounds.…”

Laser-ablated boron atoms react with GeH molecules to form novel germylidene borane HGeBH, which undergoes a photochemical rearrangement to the germanium tetrahydroborate Ge(μ-H)BH upon irradiation with light of λ = 405 nm. For comparison, the boron atom reactions with SnH only gave the tin tetrahydroborate Sn(μ-H)BH. Infrared matrix-isolation spectroscopy with deuterium substitution and the state-of-the-art quantum-chemical calculations are used to identify these species in solid argon. A planar structure of HGeBH with an electron-deficient B-Ge bond with a partial multiple bond character (bond order = 1.5) is predicted by quantum-chemical calculations. In the case of M(μ-H)BH (M = Ge, Sn) two 3c-2e B-H-M hydrogen bridged bonds are formed by donation of electrons from the B-H σ-bonds into empty p-orbitals of M.
