Synthesis and Molecular Structure of Copper Complex of Terpyridine Bearing with Imidazolium Salts

A series of functionalized terpyridine ligands containing alkyl bridged imidazolium salts were designed and prepared in convenient manner. The transition metal complexes of these functionalized terpyridine ligands were investigated and the single crystal structure of Cu complex was successfully determined by X-ray diffraction. In the copper complex, Cu²⁺ was coordinated with two terpyridine units to form distorted octahedron symmetry.
