[1,2-Bis(pyridin-2-ylmeth-oxy)benzene-κN,O,O',N']dichloridocopper(II).

Area of Science:

• Coordination Chemistry
• Crystallography
• Materials Science

Background:

• Copper(II) complexes are vital in catalysis and materials science.
• Understanding the supramolecular assembly of metal complexes informs material properties.
• Ligand design influences coordination geometry and crystal packing.

Purpose of the Study:

• To elucidate the crystal structure and supramolecular arrangement of a novel copper(II) complex.
• To investigate the coordination environment around the Cu(II) center.
• To identify intermolecular interactions driving crystal packing.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
• The coordination geometry and bonding were analyzed.
• Intermolecular interactions, including pi-pi stacking and hydrogen bonding, were identified and characterized.

Main Results:

• The title compound, [CuCl2(C18H16N2O2)], features a central Cu(II) atom in a distorted octahedral environment.
• The coordination sphere consists of two nitrogen and two oxygen atoms from the organic ligand, along with two chloride ligands.
• Adjacent molecules are linked into a chain structure through pi-pi interactions (centroid-centroid distance = 3.838 Å) and C-H...Cl hydrogen bonds.

Conclusions:

• The crystal structure of the copper(II) complex is fully characterized.
• The distorted octahedral geometry and the specific intermolecular interactions dictate the formation of a one-dimensional chain.
• This structural insight contributes to the understanding of supramolecular chemistry in copper complexes.
