Abstract:
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.

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...
