Abstract: In the title complex, diaquadinitrato[2-(4-thiazolyl)benzimidazole]copper(II), [Cu(NO₃)₂(C₁₀H₇N₃S)(H₂O)₂], the Cu atom has a distorted octahedral geometry. Thiabendazole [2-(4-thiazolyl)benzimidazole] acts as a neutral bidentate chelate, coordinating through the imidazole and thiazole N atoms. The equatorial positions are occupied by the two N atoms of the thiabendazole molecule and two O atoms of two water molecules. The axial positions are occupied by two O atoms of two nitrate ions acting as monodentate ligands. The complex units are further self-assembled into a supramolecular motif by extensive inter-ligand O-HO hydrogen bonds.
