Summary
A novel monomeric copper(II) complex was synthesized and characterized. This N-acetylanthranilate complex exhibits square-planar geometry and unique hydrogen bonding interactions involving coordinated water molecules.
Area of Science:
- Coordination Chemistry
- Inorganic Chemistry
- Crystal Engineering
Background:
- Monomeric copper(II) complexes are fundamental in coordination chemistry.
- Understanding ligand coordination and intermolecular interactions is crucial for designing novel materials.
Purpose of the Study:
- To synthesize and characterize a novel monomeric copper(II) complex.
- To investigate the coordination geometry and hydrogen bonding properties of the complex.
Main Methods:
- Single crystal X-ray diffraction was employed to determine the molecular structure.
- Spectroscopic methods were used for characterization.
Main Results:
- The complex [Cu(C(9)H(8)NO(3))(2)(H(2)O)(2)] exhibits a square-planar coordination geometry around the copper(II) ion.
- An intramolecular hydrogen bond was observed between the carboxylate group and a coordinated water molecule (O.O distance = 2.581 Å).
- The copper center possesses an inversion center.
Conclusions:
- The study presents a detailed structural analysis of a monomeric copper(II) complex.
- The findings highlight the role of N-acetylanthranilate as a ligand and the significance of hydrogen bonding in stabilizing the structure.
