Summary
This study details the crystal structure of a zinc(II) complex with phenanthroline ligands. The complex exhibits distorted trigonal-bipyramidal geometry and is stabilized by C-H⋯Cl interactions and π-π stacking.
Area of Science:
- Inorganic Chemistry
- Crystal Engineering
- Coordination Chemistry
Background:
- Zinc(II) complexes with nitrogen-containing ligands are of interest due to their diverse structures and potential applications.
- Phenanthroline ligands are versatile chelating agents used in coordination chemistry.
- Understanding the supramolecular interactions in crystal structures is crucial for materials design.
Purpose of the Study:
- To elucidate the crystal structure of the title zinc(II) complex, [Zn(2)Cl(4)(C(12)H(8)N(2))(2)].
- To analyze the coordination geometry around the zinc(II) centers.
- To investigate the intermolecular interactions stabilizing the crystal lattice.
Main Methods:
- Single-crystal X-ray diffraction analysis was employed to determine the three-dimensional structure.
- Analysis of coordination numbers and geometries around the metal centers.
- Identification and characterization of intermolecular interactions, including hydrogen bonding and π-π stacking.
Main Results:
- The crystal structure reveals two five-coordinated Zn(II) atoms, each with a distorted trigonal-bipyramidal geometry.
- The coordination sphere of each zinc(II) atom consists of two nitrogen atoms from a phenanthroline ligand and three chloride anions (one terminal, two bridging).
- The crystal lattice is stabilized by significant C-H⋯Cl interactions and intermolecular π-π stacking between phenanthroline ligands (centroid-centroid distance of 3.151(3) Å).
Conclusions:
- The study provides a detailed structural characterization of a novel zinc(II)-phenanthroline complex.
- The observed distorted trigonal-bipyramidal geometry highlights the flexibility of zinc(II) coordination.
- The identified C-H⋯Cl interactions and π-π stacking are key factors in the supramolecular assembly and crystal packing.

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...
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...

01:19Diazonium Group Substitution: –OH and –H
Nitrous acid, a weak acid, is prepared in situ via the reaction of sodium nitrite with a strong acid under cold conditions. This nitrous acid prepared in situ reacts with primary arylamines to form arenediazonium salts. Such reactions are known as diazotization reactions. As shown in Figure 1, the formation of arenediazonium salts begins with the decomposition of nitrous acid in an acidic solution to give nitrosonium ions.
01:11Aryldiazonium Salts to Azo Dyes: Diazo Coupling
The reaction of weakly electrophilic aryldiazonium (also called arenediazonium) salts with highly activated aromatic compounds leads to the formation of products with an —N=N— link, called an azo linkage. This reaction, presented in Figure 1, is known as diazo coupling and occurs without the loss of the nitrogen atoms of the aryldiazonium salt. Highly activated aromatic compounds such as phenols or arylamines favor the diazo coupling reaction. The coupling generally occurs at the para position.
01:07Ladder Diagrams: Complexation Equilibria
Ladder diagrams are useful for evaluating equilibria involving metal-ligand complexes. The vertical scale of the ladder diagram represents the concentration of unreacted or free ligand, pL. The horizontal lines on the scale depict the log of stepwise formation constants for metal-ligand complexes and indicate the dominant species in all the regions.
