Structural Characterization of a Cu(I)/Br Complex with Bis(4-(1H-Imidazol-1-Yl)Phenyl)Methanone Ligands

Resumo

The synthesis of a novel Cu(I) complex with V-shaped bidentate ligands {[Cu(BIPMO)]×[CuBr₂]}_n where BIPMO = bis(4-(1H-imidazol-1-yl)phenyl)methanone is reported. It is characterized by IR spectroscopy, elemental analysis, and single crystal X-ray diffraction. Copper(I) ions in the complex are in a distorted environment in which donor atoms are provided by the bromide anion and nitrogen atoms of BIPMO ligands, respectively. Infinite anion chains formed by CuX₄ (X = Br or N) polyhedra are linked by BIPMO ligands to give rise to layers. Furthermore, the layers are linked into 3D networks through weak intermolecular interactions.
