Tetraaquabis[4-(4-pyridyl)pyrimidine-2-sulfonato]copper(II) dihydrate

L. Li, G. Xu and H.-B. Zhu

Abstract: In the title complex, [Cu(C₉H₆N₃O₃S)₂(H₂O)₄]·2H₂O, the Cu^II atom lies on an inversion centre and is coordinated by four water molecules in equatorial positions and two N atoms from two 4-(4-pyridyl)pyrimidine-2-sulfonate ligands in apical positions. The asymmetric unit contains half of the complex and one free water molecule. The water molecules, including the uncoordinated water molecules, and sulfonate O atoms are involved in O-HO and O-HN hydrogen-bonding interactions.
