title: cis-Bis(butyl-amine-κN)bis-[sulfa-diazine(1-)-κN,N']copper(II) penta-hydrate.
abstract: In the title compound {systematic name: cis-bis-[4-amino-N-(pyrimidin-2-yl)benzene-sulfonamidato-κ(2)N,N']bis-(butyl-amine-κN)copper(II) penta-hydrate}, [Cu(C(10)H(9)N(4)O(2)S)(2)(C(4)H(11)N)(2)]·5H(2)O or [Cu(sdz)(2)(ba)(2)]·5H(2)O [ba is butyl-amine and sdz = sulfadiazine(1-)], the copper(II) cation is six-coordinated by four N atoms of two sulfadiazine ligands and two N atoms of butyl-amine ligands. The copper(II) ion and one of the water mol-ecules 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 tetra-hedral. The crystal structure involves inter-molecular 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.
