Abstract:
In the title compound, [Cu(2)(C(7)H(3)ClNO(4))(4)](n), the coordination geometry around each Cu(II) ion is distorted square-pyramidal. The CuO(5) coordination is formed by five O atoms from the carboxyl-ate groups of five 5-chloro-2-nitro-benzoate ligands. This coordination leads to the formation of centrosymmetric binuclear units which are edge-shared, forming a linear chain along the a axis, with the Cu(II) ions alternately separated by 2.5891 (4) and 3.1763 (4) Å. The chains are inter-connected into a three-dimensional network by C-H⋯O inter-actions.

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...
