The copper(II) complexes of the picolinic acid bydrazide (PH), the dipicolinic acid dibydrazide (DPH), and the 2,2'-bisacylbydrazide of 3,3'-bipyridine (DAR) ligand systems have been prepared and have been characterized by infrared spectroscopy. Coordination has been proposed to occur between the terminal amine, the amide nitrogen, and the ring nitrogen in each of the respective complexes.
Evidence for the loss of the amide hydrogen upon complexation of PH, DPH, and DAH with copper(II) has been observed by the n.m.r. study of the zinc(II) complexes of the PH and DAH ligand systems. This is in support of the structures proposed above for …
