Poly[aqua-(?2-4,4'-bipyridine-?(2) N:N')(ethane-1,2-diol-?O)(?2-sulfato-?(2) O:O')nickel(II)].

ABSTRACT: The title compound, [Ni(SO4)(C10H8N2)(C2H6O2)(H2O)] n , contains two crystallographically unique Ni(II) atoms, each lying on a twofold rotation axis and having a slightly distorted octa-hedral environment. It is isotypic with the previously reported Cu(II) analog [Zhong et al. (2011 ?). Acta Cryst. C67, m62-m64]. One Ni(II) atom is coordinated by two N atoms from two bridging 4,4'-bipyridine (4,4'-bipy) ligands, two O atoms from two sulfate ions and two aqua O atoms. The second Ni(II) atom is surrounded by two N atoms from 4,4'-bipy ligands and four O atoms, two from bridging sulfate ions and from two ethane-1,2-diol ligands. The sulfate anion acts as a bridging ligand, linking adjacent Ni(II) atoms, leading to the formation of linear ?Ni1-Ni2-Ni1-Ni2? chains along the a-axis direction. Adjacent chains are further bridged by 4,4'-bipy ligands, resulting in a two-dimensional layered polymer parallel to (001). In the crystal, the polymeric layers are linked by extensive O-H?O hydrogen-bonding inter-actions involving the O atoms of the water mol-ecules and the ethane-1,2-diol mol-ecules, resulting in a three-dimensional supra-molecular network.
