| In the title polymeric compound, [Ni(C8H5O3)2(C4H4N2)(H2O)2] n , the NiII atom is located on a twofold rotation axis and has a slightly distorted octahedral coordination sphere. In the equatorial plane, it is coordinated by two carboxylate O atoms of two symmetry-related monodentate formylbenzoate anions and by two N atoms of the bridging pyrazine ligand, which is bisected by the twofold rotation axis. The axial positions are occupied by two O atoms of the coordinating water molecules. In the formylbenzoate anion, the carboxylate group is twisted away from the attached benzene ring by 7.0(6)°, while the benzene and pyrazine rings are oriented at a dihedral angle of 66.2(3)°. The pyrazine ligands bridge the NiII cations, forming polymeric chains running along the b-axis direction. Intramolecular O - HO hydrogen bonds link the water ligands to the carboxylate O atoms. In the crystal, water-water O - HO hydrogen bonds link adjacent chains into layers parallel to the bc plane. Pyrazine-formyl C - HO hydrogen bonds link the layers, forming a three-dimensional network. There are also weak C - Hπ interactions present. The title compound is isotypic with the copper(II) complex [Çelik et al. (2014a). Acta Cryst. E70, m4-m5]. © Çelik et al. 2014. |
