摘要
The marked structural differences between the solid- and gas-phase structures of HCN ... BF3 are reproduced by ab initio calculations employing the D95 * * and 6-31 + + G * * basis sets. Specifically, the shortening in the B ... N distance and the distortion in the N ... B-F angle are reproduced to within 0.1 Angstrom and 4 degrees, respectively. The results suggest that a cooperative mechanism, where the nearest neighbour is deeply involved is responsible for the structural differences between the two states of HCN ... BF3.
