Summary
This study reveals a novel crystal structure containing copper(II) cations and copper(I) anions. These components self-assemble into layered and sandwich-like arrangements, showcasing unique coordination chemistry.
Area of Science:
- Inorganic Chemistry
- Crystal Engineering
- Coordination Chemistry
Background:
- Copper complexes exhibit diverse coordination geometries and supramolecular assemblies.
- Phenanthroline ligands are widely used in coordination chemistry due to their chelating ability.
- Understanding the self-assembly of mixed-valence copper compounds is crucial for materials science.
Purpose of the Study:
- To elucidate the crystal structure of a novel copper(II) and copper(I) compound.
- To investigate the coordination environment and supramolecular interactions within the crystal lattice.
- To characterize the self-assembly behavior of the title compound, [CuCl(C(12)H(8)N(2))(2)]·[CuCl(2)].
Main Methods:
- Single-crystal X-ray diffraction analysis was employed to determine the crystal structure.
- Analysis of coordination geometry around copper centers.
- Investigation of intermolecular interactions, such as π-π stacking.
Main Results:
- The asymmetric unit contains two distinct copper species: Cu(II) cations and Cu(I) anions.
- Cu(II) centers are coordinated by two phenanthroline ligands and a chloride anion, adopting a distorted trigonal-bipyramidal geometry.
- Cu(II) complex cations form layered structures via π-π stacking, with dichloridocuprate(I) anions situated between these layers, forming a sandwich-like architecture.
Conclusions:
- The study successfully characterized a unique crystal structure featuring mixed-valence copper.
- The observed layered and sandwich-like structures highlight the role of ligand-directed self-assembly and anion-templated interactions.
- This finding contributes to the understanding of copper coordination chemistry and crystal engineering.

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...

02:54Coordination 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.
02:34Structural Isomerism
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...

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.

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.
