Abstract

original image

O/N[BOND]H⋅⋅⋅π hydrogen bonds: Water–benzene and ammonia–benzene complexes are stabilized by the Lewis acid B(C6F5)3 and provide rare structural (X-ray) and infrared spectroscopic data for water–benzene and ammonia–benzene complexes in the solid state (see picture). The infrared spectra of the complexes showed that the O[BOND]H and N[BOND]H stretching frequencies decrease significantly on benzene complexation.
