The Cu atom in the title compound, [Cu(C 7 H 5 O 6 S)-(C 10 H 8 N 2 )](C 7 H 5 O 6 S), is chelated by the two N-heterocycles and is covalently bonded to the sulfonate O atom of the sulfosalicylate ion in a trigonal±bipyramidal geometry. The uncoordinated sulfosalicylate anion interacts with adjacent
The cation and anion of C 10 H 10 N 2 2+ ÁC 10 H 6 O 6 S 2 ## 2À Á2H 2 O lie on different twofold rotation axes in the crystal structure. The cations, anions and water molecules are connected by hydrogen bonds into a three-dimensional network structure.
