Synthesis, Structure, and Properties of Dicopper Complex With Imidazole-Containing Polyamine Ligand

Abstract

A new dicopper complex [Cu₂(L)(N₃)₂](ClO₄)₂·4H₂O (1) with imidazole-containing macrocyclic polyamine ligand was synthesized, and characterized by elemental analysis, FT-IR, UV-Vis, TGA, single-crystal X-ray diffraction, and PXRD. Complex 1 crystallizes in monoclinic, space group P2₁/c. The coordination geometry around Cu(II) atom is five-coordinated distorted trigonal-bipyramid, and the imidazole-pendants and the azide anions are located on the different sides of the macrocyclic ligand.
