Thiabendazolium Nitrate, an Anthelmintic Compound

In the crystal structure of 2-(thiazol-4-yl)-1H-benzimidazolium nitrate, C 10 H 8 N 3 S + .NO - 3 , the benzimidazole moiety is protonated. The benzimidazole and thiazole systems are coplanar. Both N-H groups of the protonated benzimidazole are involved in N-H…O hydrogen bonds with the nitrate anion.
