Abstract:
In the title complex, [Co(NCS)(2)(C(16)H(16)N(2)O(2))], the Co(II) ion is coordinated by two N atoms from one 2,9-dieth-oxy-1,10-phenanthroline ligand and two N atoms from two different thio-cyanate ligands in a distorted tetra-hedral environment. The Co-N bonds involving the thio-cyanate ligands are significantly shorter than the other two Co-N bonds. The atoms of one of the eth-oxy groups are essentially coplanar with the phenanthroline ring [N=C-O-C = 178.8 (4)°], while the other eth-oxy group is slightly twisted from the phenanthroline ring plane [N=C-O-C = 167.2 (4)°]. In the crystal structure, there is a weak π-π stacking inter-action between two symmetry-related phenanthroline rings with a centroid-centroid distance of 3.706 (4) Å.

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.
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...
