Area of Science:

• Inorganic Chemistry
• Coordination Chemistry
• Crystallography

Background:

• Copper(II) complexes are crucial in various catalytic and biological processes.
• Understanding coordination geometries is key to predicting complex reactivity and properties.
• Pyridazine-based ligands offer unique electronic and steric properties for metal coordination.

Purpose of the Study:

• To synthesize and characterize a novel copper(II) complex with pyridazine ligands.
• To elucidate the coordination geometry and electronic structure of the copper(II) ion.
• To investigate the structural features of the [CuCl(C16H14N4)2]ClO4 complex.

Main Methods:

• Synthesis of the title compound, [CuCl(C16H14N4)2]ClO4.
• Single-crystal X-ray diffraction analysis to determine the molecular structure.
• Spectroscopic characterization (e.g., UV-Vis, IR) to confirm composition and bonding.

Main Results:

• The crystal structure reveals a mononuclear copper(II) complex cation and a perchlorate anion.
• The copper(II) ion adopts a trigonal bipyramidal coordination geometry.
• The equatorial plane consists of a chloride atom and two nitrogen atoms from pyridazine rings, while axial positions are occupied by nitrogen atoms from methylpyridine rings.

Conclusions:
