The title crystal structure, {[Cu(SO4)(C6H6N2O)(H2O)(2)]-H2O} 6, is a monoclinic polymorph of the previously reported triclinic structure [Sieron & Bukowska-Strzyz. ewska (1999). Acta Cryst. C55, 491-494] in which sulfate ligands bridge six-coordinate Cu atoms, generating an extended one-dimensional chain structure along [010]. Neighboring chains are connected by N-(HO)-O-...(sulfate) hydrogen bonds into ladders, which are further connected into two-dimensional layers perpendicular to the [100] direction by N-(HO)-O-...(water) and O(water)-(HO)-O-... hydrogen bonds. These layers are connected by O-(HO)-O-... hydrogen bonds into a three-dimensional network.
