Abstract:
In the title polymer, {[Co(C(14)H(10)N(2)O(4))(H(2)O)]·3.5H(2)O}(n), the Co(2+) ion is coordinated by three carboxyl-ate O atoms from two 5-[(pyridin-2-ylmeth-yl)amino]-isophthalate anions, two N atoms from a (pyridin-2-ylmeth-yl)amino group and an O atom from a water mol-ecule, furnishing a distorted CoO(4)N(2) octa-hedral geometry. Each anion acts as a μ(3)-bridge, linking cobalt ions into a two-dimensional layer parallel to (100). The asymmetric unit also contains three and a half solvent water mol-ecules, which could not be modeled. Therefore, the diffraction contribution of the solvent water mol-ecules was removed by the subroutine SQUEEZE in PLATON [Spek (2009). Acta Cryst. D65, 148-155]. The crystal structure is stabilized by O-H⋯O hydrogen bonds in which the coordinated water mol-ecule acts as donor and the carboxyl-ate O atoms as acceptors.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.

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...
