Abstract

In the title compound {systematic name: cis-bis[4-amino-N(pyrimidin-2-yl)benzenesulfonamidato-kappa N-2,N']bis(butylamine-kappa N)copper(II) pentahydrate}, [Cu(C10H9N4O2S)(2)(C4H11N)(2)]center dot 5H(2)O or [Cu(sdz)(2)(ba)(2)]center dot 5H(2)O [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 center dot center dot center dot N and N-H center dot center dot center dot O hydrogen bonds. N-H center dot center dot center dot N hydrogen bonds between sdz ligands lead to a sheet structure parallel to the ab plane.
