Abstract
Density functional theory method is used to examine a series of group III triazides X(N3)3 (X = B, Al, Ga). These compounds, except for the C3h planar B(N3)3 and Al(N3)3, are first reported here. C3h planar structures are the most energetically favored for all singlet X(N3)3 systems. Potential-energy surfaces for unimolecular decompositions of the C3h and CS planar X(N3)3 species have been investigated. Results show that decomposition of B(N3)3 obeys sequential fashion and follows a four-step mechanism: (1) B(N3)3 → NB(N3)2 + N2; (2) NB(N3)2 → cyc-N2BN3 + N2; (3) cyc-N2BN3 → trigonal-BN3 + N2; (4) trigonal-BN3 → linear-NBNN. Decomposition of Al(N3)3 follows a two-step mechanism: (1) Al(N3)3 → NAl(N3)2 + N2; (2) NAl(N3)2 → linear-AlN3 + 2N2. The dissociation of Ga(N3)3 follows only one-step mechanism: Ga(N3)3 → angular-GaN3 + 3N2. These findings may be helpful in understanding the decomposition mechanisms of group III triazides as well as the possible mechanism for XN film generation. © 2014 Wiley Periodicals, Inc.
