In the title complex, [CuCl(2)(C(10)H(7)N(3)S)(C(2)H(5)OH)], the Cu(II) ion is five-coordinated in a distorted square-pyramidal geometry by two N atoms from a 2-(1,3-thia-zol-4-yl)-1H-benzimidazole ligand, one O atom from an ethanol mol-ecule and two Cl atoms. In the crystal, O-H⋯Cl and N-H⋯Cl hydrogen bonds link the complex mol-ecules into a layer parallel to (100). π-π inter-actions between the thia-zole rings are observed [centroid-centroid distance = 3.749 (3) Å].
