A hydrogen-bonded supramolecular chain in thiabendazolium perchlorate

N. Stanley, P. Panneerselvam and P. Thomas Muthiah

Abstract: In the title compound, thiabendazolium perchlorate [2-(4-thiazolyl)-1H-benzimidazol-1-ium perchlorate], C₁₀H₈N₃S⁺·ClO₄^-, one of the N atoms of the benzimidazole moiety is protonated rather than that in the thiazole group. This protonation leads to equalization of the bond angles at the two N atoms of the benzimidazole group. The C-C bond connecting the two ring systems has a length of 1.455 (7) Å. The dihedral angle between the benzimidazole system and the thiazole ring is 10.4 (3)°. The perchlorate anions bridge the thiabendazolium cations through a pair of N-HO hydrogen bonds, leading to a hydrogen-bonded supramolecular chain.
