Abstract:
The ortho-rhom-bic (space group Pna21) unit cell of the title compound, [CoCl2(C13H10N2O2)2]·CH3OH·H2O, contains eight complex mol-ecules, four A and four B, along with sixteen solvent mol-ecules of crystallization. The two independent CoII atoms are coordinated by imine and pyridine N atoms from each of two neutral pyridinyl-imino-benzoic acids and two cis-chlorido ligands in a distorted octa-hedral coordination environment. In the crystal, the complex mol-ecules pack loosely with the closest Co⋯Co separation exceeding 7.7 Å. The uncoordinated carb-oxy-lic groups on the ligands are presumably hydrogen-bonded to the solvent methanol and water mol-ecules.

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...

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...
