Abstract
In the title compound {systematic name: cis-bis[4-amino-N-(pyrimidin-2-yl)benzenesulfonamidato-κ2 N,N′]bis(butylamine-κN)copper(II) pentahydrate}, [Cu(C10H9N4O2S)2(C4H11N)2]·5H2O or [Cu(sdz)2(ba)2]·5H2O [ba is butylamine and sdz = sulfadiazine(1−)], the copper(II) cation is six-coordinated by four N atoms of two sulfadiazine ligands and two N atoms of butylamine ligands. The copper(II) ion and one of the water molecules lie on twofold rotation axes. One of the butyl groups is disordered over two sites, with occupancies of 0.395 (8) and 0.605 (8). The geometry around the S atom is distorted tetrahedral. The crystal structure involves intermolecular N—H⋯N and N—H⋯O hydrogen bonds. N—H⋯N hydrogen bonds between sdz ligands lead to a sheet structure parallel to the ab plane.
