Area of Science:

• Coordination Chemistry
• Crystal Engineering
• Organometallic Chemistry

Background:

• Copper(I) complexes are versatile in catalysis and materials science.
• Tropolonate ligands offer unique coordination properties.
• Understanding intermolecular forces is key to crystal structure prediction.

Purpose of the Study:

• To characterize the crystal structure of a novel copper(I) complex.
• To investigate the coordination behavior of the 3,5,7-tribromotropolonate ligand.
• To analyze the intermolecular interactions governing crystal packing.

Main Methods:

• Single-crystal X-ray diffraction analysis was performed.
• The coordination geometry around the copper(I) center was determined.
• Intramolecular and intermolecular interactions were identified and analyzed.

Main Results:

• The copper(I) atom resides on a twofold rotation axis.
• The tribromotropolonate anion acts as a bidentate ligand with a bite angle of 76.42(9)°.
• Intramolecular C-H⋯O interactions and extensive weak C-H⋯π interactions were observed, leading to a herringbone packing.

Conclusions:

• The study provides detailed structural insights into a novel copper(I) complex.
• The coordination mode and intermolecular interactions dictate the observed crystal structure.
• This work contributes to the understanding of structure-property relationships in copper complexes.
