cis-Bis(butylamine-kappa N)bis[sulfa-Diazine(1-)-kappa N-2,N ']copper(II) Pentahydrate

Abstract

In the title compound {systematic name: cis-bis-[4-amino-N-(pyrimidin-2-yl) benzene-sulfonamidato-2 N,N′]bis-(butyl-amine-N)copper(II) penta-hydrate}, [Cu(C10H9N4O2S)2(C4H11N)2]·5H2O or [Cu(sdz)2(ba)2] ·5H2O [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.
