This study details a mononuclear copper(II) complex with a distorted square-planar geometry. The copper atom is coordinated by Schiff base ligands, revealing specific bond lengths and ring orientations.
Area of Science:
- Inorganic Chemistry
- Coordination Chemistry
- Materials Science
Background:
- Schiff base ligands are versatile in coordination chemistry.
- Copper(II) complexes exhibit diverse structural and electronic properties.
- Understanding metal-ligand interactions is crucial for designing new materials.
Purpose of the Study:
- To synthesize and characterize a novel mononuclear copper(II) complex.
- To elucidate the coordination geometry and bonding characteristics.
- To investigate the structural features of the copper(II) complex with Schiff base ligands.
Main Methods:
- Single-crystal X-ray diffraction analysis.
- Synthesis of the mononuclear copper(II) complex.
- Spectroscopic characterization (though not detailed in the abstract).
Main Results:
- The copper(II) atom adopts a slightly distorted square-planar geometry.
- Coordination involves N and O atoms from two deprotonated Schiff base ligands.
- Specific Cu-N (2.009(2) Å) and Cu-O (1.888(2) Å) bond lengths were determined.
- The dihedral angle between cyano-phenyl and phenolate rings is 42.28(13)°.
Conclusions:
- The synthesized complex exhibits a well-defined mononuclear copper(II) structure.
- The coordination environment is dictated by the Schiff base ligand architecture.
- The structural data provides insights into copper(II) coordination chemistry.

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.
