Structure and Stability of Hydrogen Compounds of Group 13/15 Elements Stabilized with Lewis Acids and Bases

Structures and Stability of Mixed Main Group Hydrides [PBEH6]n (E = C, Si, Ge; n = 1–4) and Donor–Acceptor Stabilization of Monomeric Chain Isomers

“…In complexes with the transition metal carbonyls, there is an additional bonding between acceptor atom of the chain hydride and carbonyl groups or the transition metal with formation of six-membered cycles for M­(CO) 5 (M = Cr, Mo, W) (Figure e) and four-membered cycles for Fe­(CO) 4 (Figure f). Similar additional interactions were reported for the LA-stabilized 13–15 hydrides. , …”

“…Similar additional interactions were reported for the LA-stabilized 13−15 hydrides. 35,36 The halogen atom migration (Figure 4c) is related to an effective interaction of F, Cl, and Br with SiH 2 LUMO with subsequent dissociation of one B−X bond, despite the fact that the Si−X bond energies are lower than those for B−X. 34 The boron environment becomes planar in this case.…”
