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
