The infrared spectra of the title compounds have been reported. The spectral data suggest that the host framework of these compounds are similar to those of the en-T-d-type clathrate compounds. There is good evidence for hydrogen bonding from ligand molecules to benzene molecules as a pi to sigma hydrogen bond.
