ร2CH 2 Cl 2 , from a methanol-dichloromethane solution yields a 1:2 inclusion compound with dichloromethane. The host-guest compound crystallizes with one host and two guest molecules in the asymmetric unit. The molecular geometry is stabilized by intramolecular O-Hร ร รO hydrogen bonds, whereas the
1H NMR spectral examinations revealed that the title compound, which was previously proposed to be conformationally-frozen, is not truly immobilized but the rate of the conformational change is just slower than that of the NMR time-scale.
