The title compound, [Cu(2)(SO(4))(2)(C(10)H(8)N(2))(2)(C(2)H(6)O(2))(2)(H(2)O)(2)](n), contains two crystallographically unique Cu(II) centres, each lying on a twofold axis and having a slightly distorted octahedral environment. One Cu(II) centre is coordinated by two bridging 4,4'-bipyridine (4,4'-bipy) ligands, two sulfate anions and two aqua ligands. The second is surrounded by two 4,4'-bipy N atoms and four O atoms, two from bridging sulfate anions and two from ethane-1,2-diol ligands. The sulfate anion bridges adjacent Cu(II) centres, leading to the formation of linear ···Cu1-Cu2-Cu1-Cu2··· chains. Adjacent chains are further bridged by 4,4'-bipy ligands, which are also located on the twofold axis, resulting in a two-dimensional layered polymer. In the crystal structure, extensive O-H···O hydrogen-bonding interactions between water molecules, ethane-1,2-diol molecules and sulfate anions lead to the formation of a three-dimensional supramolecular network structure.

1. Phenylethane-1,2-diol 2-acetate has been isolated from the incubation of styrene oxide or styrene diol with liver microsomes of phenobarbital-pretreated rabbits. 2. Observed ratios of phenylethane-1,2-diol to its 2-acetate in the incubation mixtures ranged between 19 : 1 and 5 : 1 with different microsomal preparations and different periods of incubation. 3. The formation of phenylethane-1,2-diol 2-acetate may be a source of errors in the radiometric determination of epoxide hydrase activity in microsomes.
3. 3-(3,5-Dichlorophenyl)benzene-1,2-diol

The title structure [systematic name: 4-(3,5-dichlorophenyl)benzene-1,2-diol], C12H8Cl2O2, is a putative metabolite of 3,5-dichlorobiphenyl (PCB 14). The dihedral angle between the two benzene rings of the title compounds is 58.86 (4)°. In the crystal, it displays intra and intermolecular O-H···O hydrogen bonding and intermolecular O-H···Cl hydrogen···chlorine interactions.
