N2 - Structures and stability of mixed group 13−14−15 element hydridesPBEH6 (E = C, Si, Ge), their oligomers, and complexes with Lewis acids and Lewisbase are computationally studied at the B3LYP-D3/def2-TZVP level of theory.Unsubstituted chain hydrides are unstable and are expected to form cyclic oligomers.Cyclization can be prevented by the donor−acceptor complex formation. Forcomplexes of chain hydrides with Lewis acid in many cases additional reactivitybeyond the donor−acceptor complex formation is observed: cyclization andmigration of terminal group from the group 13 Lewis acid to the boron or group14 terminal atoms of the hydride. The most promising compounds for theexperimental studies have been identified. Joint stabilization by both W(CO)5 and trimethylamine provides a synergetic effect,allowing stabilization of 13−14−15 chain compounds.
