Tetraaquabis[2-(4-pyridyl)ethanesulfonato-N]copper(II)

Q.-W. Zhang and Y.-H. Wen

Abstract: The centrosymmetric title compound, [Cu(C₇H₈O₃S)₂(H₂O)₄], forms a pillared hydrogen-bonded layered network. The coordination geometry of the Cu^II ion is distorted octahedral, involving four aqua ligands and two N-atom donors of two 2-(4-pyridyl)ethanesulfonate (PES) ligands. The sulfonate group of PES is not involved in coordination to the metal, but participates in hydrogen bonds with the aqua ligands.
