1Institute of Physical Chemistry, Peking University, Beijing 100871, People's Republic of China.
Summary
Tetracarbonyl(4,7-diphenyl-1,10-phenanthroline-N,N')molybdenum(0) exhibits a distorted octahedral coordination. This molybdenum complex demonstrates improved solubility compared to its unsubstituted phenanthroline analog.
Area of Science:
- Organometallic Chemistry
- Coordination Chemistry
- Molybdenum Complexes
Background:
- 1,10-phenanthroline ligands are crucial in coordination chemistry.
- Molybdenum carbonyl complexes are studied for their unique properties.
Purpose of the Study:
- To synthesize and characterize tetracarbonyl(4,7-diphenyl-1,10-phenanthroline-N,N oun)molybdenum(0).
- To investigate the structural and solubility properties of the novel molybdenum complex.
Main Methods:
- Synthesis of the molybdenum complex [Mo(C24H16N2)(CO)4].
- Structural analysis using X-ray crystallography to determine coordination geometry.
- Solubility tests in various solvents.
Main Results:
- The synthesized complex, [Mo(C24H16N2)(CO)4], displays a distorted octahedral geometry around the molybdenum atom.
- Two carbonyl (CO) ligands are cis to each other and trans to nitrogen atoms of the dpphen ligand.
- The other two CO ligands are trans to each other and occupy axial positions.
- The diphenyl-substituted phenanthroline ligand enhances the solubility of the complex compared to the unsubstituted analog [Mo(phen)(CO)4].
Conclusions:
- The diphenyl substitution on the 1,10-phenanthroline ligand significantly improves the solubility of tetracarbonylmolybdenum(0) complexes.
- The structural data provides insights into the coordination preferences of substituted phenanthroline ligands in molybdenum carbonyls.

02:51Metal-Ligand Bonds
The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
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...

For transition metal complexes, the coordination number determines the geometry around the central metal ion. Table 1 compares coordination numbers to molecular geometry. The most common structures of the complexes in coordination compounds are octahedral, tetrahedral, and square planar.

Isomerism in Complexes
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...

02:42Valence Bond Theory
Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from which they are composed. In an attempt to explain the bonding and structure of coordination complexes, Linus Pauling proposed the valence bond theory, or VBT, using the concepts of hybridization and the overlapping of the atomic orbitals. According to VBT, the central metal atom or ion (Lewis acid) hybridizes to provide empty orbitals of suitable...
03:02Colors and Magnetism
Color in Coordination Complexes
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.

00:43Complexometric Titration: Ligands
Different monodentate and polydentate ligands are used as complexing agents in complexometric titration reactions. The formation of complexes by mono- and bidentate ligands involves two or more intermediate steps, limiting their use as complexing agents. In comparison, polydentate ligands can form complexes with metal ions in a single-step process, facilitating sharper end points. This means polydentate ligands, such as amino carboxylic acid derivatives, are most commonly employed in...
