Crystal structure and Hirshfeld surface analysis of aqua-bis-(nicotinamide-κ)bis-(4-sulfamoylbenzoato-κ)copper(II).

In the crystal of the title complex, [Cu(CHNOS)(CHNO)(HO)], the Cu cation and the O atom of the coordinated water mol-ecule reside on a twofold rotation axis. The Cu ion is coordinated by two carboxyl-ate O atoms of the two symmetry-related 4-sulfamoylbenzoate (SB) anions and by two N atoms of the two symmetry-related nicotinamide (NA) mol-ecules at distances of 1.978 (2) and 2.
