Abstract: Two dinuclear Cu^II complexes based on a diazecine ligand were characterized by X-ray diffraction, one of which includes the rare Cu^II–F bond, resulting from dissociation of a BF₄⁻ ion. The F⁻ ligands actively participate in the crystal structure, behaving as acceptors for hydrogen bonding.

Keywords: copper; diazecine; hydrogen bond
