Abstract

A series of 9-imino-imidazo[1,2-h][1,7]naphthyridine ligands and their nickel complexes were synthesized and structurally characterized by single-crystal X-ray crystallography. X-ray diffraction analysis revealed that 9-imino-imidazo[1,2-h][1,7]naphthyridines were used as tridentate ligands in...
