Purpose of the Study:

• To synthesize and characterize a new copper(II) complex with imidazole and trichloro-acetate ligands.
• To investigate the coordination geometry and crystal packing of the title compound.
• To elucidate the role of hydrogen bonding and halogen bonding in stabilizing the crystal structure.

Main Methods:

• Single-crystal X-ray diffraction was used to determine the molecular and crystal structure.
• The synthesis involved the reaction of imidazole with trichloro-acetatocopper(II).
• Structural analysis focused on coordination environment, hydrogen bonding, and intermolecular contacts.

Main Results:

• A novel copper(II) complex, [Cu(C(2)Cl(3)O(2))(2)(C(3)H(4)N(2))(4)], was successfully synthesized.
• The copper(II) ion exhibited a distorted octahedral coordination geometry.
• The crystal structure is stabilized by N-H⋯O hydrogen bonds and significant intermolecular Cl⋯Cl contacts (3.498 Å).

Conclusions:

• The study presents a new coordination compound with interesting structural features.
• Hydrogen bonding and halogen bonding play crucial roles in the self-assembly and stability of the crystal lattice.
• This work contributes to the understanding of supramolecular chemistry in copper(II) complexes.
