Dynamic parameters of the hypervalent O3B...O bond

The results of investigations of the common and distinctive features of var ious chemical bonds, including intermolecular bonds, were considered. The g eometries, atom charges, and force constants of the bonds in a dependent sy stem of coordinates were calculated for five boroxide molecular species usi ng the MINDO/3 method. The correlations found between the force constants a nd the bond energies in the O3B...O bridge were compared with the analogous relations for the OH...O bridge.
