Stability and Electronic Structure of Donor-Acceptor Stabilized Group 13/15 Oligomers.

Electronic structures and thermodynamic characteristics of chain inorganic group 13-15 oligomers [H2MEH2]n (M = B, Al, Ga, E = P, As; n = 4-15) are presented. Donor-acceptor interaction with both Lewis acids and Lewis bases effectively stabilizes chain isomers with respect to spontaneous cyclization and significantly changes their electronic structure.
