Abstract:
The synthesis and characterization of mercapto-porphyrin and its cobalt(II) complex are reported. A new method was used to synthesize the porphyrin. These compounds have not been reported previously. Their structural assignment of the porphyrin and its cobalt(II) complex were based on the elemental analysis, UV-Vis, IR and 1H NMR spectra. The elemental analysis data for C44H30N4H4 was C, 69.32(69, 44) H, 4.30(4.24) N, 7.35(7.36). The data of UV-Vis spectra indicated that soret and Q bands of the TMTBP displayed a red-shift in comparison with TPP. The IR spectra of TMTBP showed that the peak of delta (N-H) disappeared, when the cobalt(II) complex was formed. The 1H NMR spectra proved that a new mercapto-porphyrin has been synthesized. This paper also reported electrochemical behavior of new compounds in DMSO by cyclic voltammetry and differential pulse voltammetry.

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...

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.
Stereoisomerism
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...
