Aqua-(hippurato)bis-(1,10-phenanthroline)cobalt(II) nitrate monohydrate
Abstract:
In the title compound, [Co(C(9)H(8)NO(3))(C(12)H(8)N(2))(2)(H(2)O)]NO(3)·H(2)O, the Co(II) atom is six-coordinated by a carboxylate O atom of the hippurate (Hc) anion, a water O atom and four N atoms from two 1,10-phenanthroline ligands in a distorted octa-hedral geometry. The uncoordinated O atom of the hippuric acid anion is involved in an intra-molecular hydrogen bond to the coordinated water mol-ecule. The crystal packing is stabilized by inter-molecular O-H⋯O hydrogen bonds involving the Hc anions, the coordinated water mol-ecule, the nitrate anion and the uncoordinated water mol-ecule.

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...

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...
