Aqua-(picolinato N-oxide-κO,O)(pyridine-2,6-dicarboxyl-ato-κO,N,O')iron(III) monohydrate
Abstract:
In the title compound, [Fe(C(6)H(4)NO(3))(C(7)H(3)NO(4))(H(2)O)]·H(2)O, the Fe(III) ion is coordinated by two O and one N atoms from a pyridine-2,6-dicarboxyl-ate ligand, by two O atoms from a picolinate N-oxide ligand and by one water O atom in a distorted octa-hedral geometry [Fe-O = 1.940 (3)-2.033 (3) Å and Fe-N = 2.057 (4) Å]. In the crystal structure, the coordinated and solvent water mol-ecules contribute to the formation of O-H⋯O hydrogen bonds, which link the mol-ecules into layers parallel to the ab plane.

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...
