Dichlorido[2,2'-(oxydimethyl-ene)dipyridine]copper(II).

Area of Science:

• Coordination Chemistry
• Crystal Engineering
• Supramolecular Chemistry

Background:

• Copper(II) complexes are vital in catalysis and materials science.
• Understanding intermolecular interactions is key to designing functional materials.
• Pyridine-containing ligands offer versatile coordination and stacking properties.

Purpose of the Study:

• To elucidate the crystal structure and intermolecular interactions of the novel copper(II) complex, [CuCl(2)(C(12)H(12)N(2)O)].
• To investigate the coordination geometry around the Cu(II) ion.
• To analyze the role of π-π stacking and metal-ligand interactions in the solid state.

Main Methods:

• Single-crystal X-ray diffraction analysis.
• Analysis of coordination geometry and bond distances.
• Investigation of non-covalent interactions, including π-π stacking and Cu⋯centroid contacts.

Main Results:

• The copper(II) ion adopts a distorted trigonal-bipyramidal coordination environment.
• Weak π-π stacking interactions were observed between symmetry-related pyridine rings (centroid-to-centroid distance of 3.8134(17) Å).
• A close contact was found between the pyridine π-system and a symmetry-related Cu(II) ion (Cu⋯centroid distance of 3.868 Å).

Conclusions:

• The crystal structure of [CuCl(2)(C(12)H(12)N(2)O)] is characterized by specific coordination and intermolecular interactions.
• These interactions, including π-π stacking and metal-π interactions, contribute to the overall crystal packing.
• The findings provide insights into the supramolecular assembly of copper(II) complexes with pyridine-based ligands.
