1College of Biological and Chemical Sciences Engineering, Jiaxing University, Jiaxing Zhejiang 314001, People's Republic of China.
Abstract:
The title complex, [Cu(C(13)H(10)ClN(2)O)(H(2)O)]NO(3)·H(2)O, was obtained by the reaction of 5-chloro-salicyl-aldehyde, 2-(amino-meth-yl)pyridine and copper nitrate in methanol. The first reported polymorph of this complex was triclinic [Liang et al. (2010 ▶). Acta Cryst. E66, m40]. The present polymorph crystallized in the monoclinic space group P2(1)/c. The Cu(II) ion is in a square planar environment and is coordinated by one phenolate O, one imine N and one pyridine N atom of the tridentate Schiff base ligand and by one water O atom. In the crystal, mol-ecules are linked through inter-molecular O-H⋯O hydrogen bonds to form chains along the a axis.

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...
