摘要

Recrystallization of the anthelmintic drug mebendazole from propionic acid yields a 1:1 molecular complex which crystallizes in the triclinic system space group P (1) over bar, a 5.928(2), b = 11.066(2), c = 14.337(6)Angstrom, alpha = 94.89(3), beta = 101.56(3), gamma = 96.18(2)degrees, and Z = 2 complex units in the unit cell. An x-ray diffraction study revealed an R-2(2)(8) hydrogen bonding system in the complex, involving the unprotonated imidazole N and amide N-H function of the drug and the acid carboxylic group. Complex molecules form centrosymmetric dimers by intermolecular N-H ... O hydrogen bonding involving the protonated imidazole N atom and the benzoyl O atom of the drug molecule. [References: 13]
