Summary
This study details the crystal structure of a novel copper(II) complex, [Cu(NO3)2(C24H16N2)2]. The copper ion exhibits eight-coordinate geometry within a distorted octahedral-like polyhedron, influenced by diphenylphenanthroline and nitrate ligands.
Area of Science:
- Inorganic Chemistry
- Crystallography
- Coordination Chemistry
Background:
- Copper(II) complexes with nitrogen-containing ligands are of interest due to their diverse applications.
- Understanding the coordination environment of metal ions is crucial for predicting complex properties.
Purpose of the Study:
- To elucidate the detailed crystal structure and coordination geometry of a novel copper(II) complex.
- To characterize the bonding interactions between the copper(II) ion, diphenylphenanthroline, and nitrate ligands.
Main Methods:
- Single-crystal X-ray diffraction analysis was employed to determine the molecular and crystal structure.
- The crystallographic data were analyzed to identify the coordination polyhedron and molecular symmetry.
Main Results:
- The copper(II) cation is eight-coordinate, forming a distorted octahedral-like polyhedron.
- Two diphenylphenanthroline ligands chelate the copper ion, defining a distorted CuN4 equatorial plane.
- Two bidentate nitrate groups occupy the axial positions, exhibiting weak coordination.
Conclusions:
- The complex [Cu(NO3)2(C24H16N2)2] crystallizes in the monoclinic space group C2/c.
- The molecule possesses C2 point-group symmetry, with a twofold axis passing through the copper(II) cation.
- The structural characterization provides insights into the coordination behavior of copper(II) with bulky N-donor ligands and nitrate anions.

02:57Coordination Number and Geometry
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.
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...

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...
02:54Coordination Compounds and Nomenclature
In most main group element compounds, the valence electrons of the isolated atoms combine to form chemical bonds that satisfy the octet rule. For instance, the four valence electrons of carbon overlap with electrons from four hydrogen atoms to form CH4. The one valence electron leaves sodium and adds to the seven valence electrons of chlorine to form the ionic formula unit NaCl (Figure 1a). Transition metals do not normally bond in this fashion. They primarily form coordinate covalent bonds, a...
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.

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...
