Abstract:
The title complex, [Co(C(15)H(12)N(3)O(2)S)(2)], consists of an octahedrally coordinated Co(II) ion, with two crystallographically independent 1,4-dibenzoylthiosemicarbazidate ligands in a tridentate mer coordination [Co-O = 2.064 (3)-2.132 (3) A and Co-N = 2.037 (3)-2.043 (3) A]. There are intermolecular N-H...S hydrogen bonds involving one ligand and strong pi-pi stacking interactions involving the other ligand, resulting in a three-dimensional supramolecular framework. The hydrogen bonds and pi-pi interactions, as well as different intramolecular aryl-benzamide H-C...H(-N) distances, give rise to a difference in conformation between the two ligands.

03:02Colors 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.
02:34Structural 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...

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...

Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...
