摘要

Ab initio calculations at theMP2/6-311++G(d,p) computational level were used to analyze the interactions between amolecule of B _2H _6 with some smallmoleculeswhich often have both hydrogen bond acceptor (HBA) and hydrogen bond donor (HBD) abilities. Interaction of B _2H _6 with amine derivatives (NH _3, NH _2Me, NHMe _2, NMe _3) as well as H _2O, MeOH, OMe _2, and CH _3CN occurs through its bridged protons (Hb) to form a H _b..X (X = N or O) hydrogen bond complex. On the other hand, interaction of B _2H _6 with HCN could be as Ht..H dihydrogen bond or H _b..N hydrogen bonding. Topological analyses of the electron density of optimized structures have been carried out using the atoms in molecules (AIMs) methodology. AIM calculations are indicating the HBD characteristic of Hb of B _2H _6 in its hydrogen bond interaction with X atom of HBA molecules. Stability of the predicted clusters depends on the kind ofHBAmolecule. In addition, our calculations have been used to determine the Drago-Wayland coefficients of diborane and stabilization energy of adducts formed by the association of the diborane and HBAs.
