Synthesis and structural characterization of two copper complexes with long rigid ligands

摘要

Two copper complexes with long rigid ligands, Cu(Tta)(2)(L-1) (I), and Cu(Tta)(2)(L-2) (II), where L-1 = (E)-3-(4-(1H-benzo[d]imidazol-1-yl)-(4-phenyl)phenyl)-1-phenylprop-2-en-1-one, L-2 = (E)-3-(4-(1H-imidazol-1-yl)phenyl)-1-(4-phenyl)phenyl)prop-2-en-1-one), have been synthesized and characterized. The single-crystal X-ray analysis (CIF files CCDC nos. 1409671 (I) and 1409672 (II)) for complexes I and II demonstrates that each copper ion assumes a distorted square-pyramidal MO4N polyhedron in which four oxygen atoms come from the Tta ligands, and one nitrogen atom comes from the N-donor ligand. Both of the complexes are linked into 3D networks through weak intermolecular interactions.
