The title compound, [Ni(SO4)(C10H8N2)(C2H6O2)(H2O)] n , contains two crystallographically unique NiII atoms, each lying on a twofold rotation axis and having a slightly distorted octahedral environment. It is isotypic with the previously reported CuII analog [Zhong et al. (2011). Acta Cryst. C67, m62-m64]. One NiII 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 interactions involving the O atoms of the water molecules and the ethane-1,2-diol molecules, resulting in a three-dimensional supramolecular network. © 2013 Kai-Long Zhong.

The title compound, [Zn(SO4)(C10H8N 2)2]·C2H6O2, is a six-coordinate zinc(II) complex with a distorted octa-hedral coordination geometry. The ZnII atom is bonded by two O atoms of the bidentate chelating sulfate ligand and four N atoms of the two chelating 2,2'-bipyridine ligands. The Zn - N bond distances range from 2.1287 (17) to 2.1452 (17) Å and the Zn - O bond distance is 2.1811 (15) Å. The two chelating NCCN groups subtend a dihedral angle of 81.1 (1)°. In the crystal structure, the [ZnSO4(C10H8N2)2] and C2H6O2 units are connected by inter-molecular O - H⋯O hydrogen bonding, which leads to additional stabilization of the structure. Source

The title compound, [Cd(C12H8N2) 2(H2O)2]SO4·6H2O, was obtained unexpectedly during an attempt to synthesize a cadmium complex with bidentate bridging sulfate ligands via hydrothermal synthesis. The Cd II metal ion is six-coordinated by two chelating 1,10-phenanthroline ligands and two water molecules, resulting in a distorted octahedral geometry for the metal ion. The two chelating N2C2 groups are almost perpendicular to each other [dihedral angle = 86.75 (2)°]. In the crystal, the [Cd(C12H8N2)2(H 2O)2]2+ complex cations join with the sulfate anions through two Owater - H⋯Osulfate hydrogen bonds. These ion pairs are further inter-linked into a two-dimensional supermolecular structure via additional O - H⋯O hydrogen bonds. © Kai-Long Zhong 2011. Source

The title compound, [Co(SO4)(C12H8N 2)2]·C3H8O2, was obtained unexpectedly as a by-product during an attempt to synthesize a mixed-ligand complex of CoII with 1,10-phenanthroline (phen) and melamine via a solvothermal reaction. The CoII metal ions are in a distorted octa-hedral coordination environment formed by four N atoms from two chelating phen ligands and two O atoms from a bidentate sulfate ligand. The two chelating N2C2 groups are almost perpendicular to each other [dihedral angle = 80.06 (8)°]. A twofold rotation axis passes through the Co and S atoms, and also through the central C atom of the propane-1,3-diol solvent mol-ecule. Inter-molecular O - H⋯O hydrogen bonds help to stabilize the structure. Source
