Reactions of 2-acetylpyridine aminoguanidine with Cu(II) under different reaction conditions

Aminoguanidine derivatives are the focus of research because their various biological activities, such as antiviral, antibacterial, analgesic, antioxidant, and anticancer. Their complexes with different metals also examined many them show significant activity, too. Besides, some good photoluminescent properties used for preparation photoelectronic devices. In accordance, synthesis, physicochemical, structural, thermal characterization 2-acetylpyridine aminoguanidine (L) copper(II) is described here. Under reaction conditions, Cu(II) L gives three compositions. By varying strength basicity deprotonating agent used, it was proven here that Schiff base could be coordinated in neutral or monoanionic form. presence pyridine, a coordination polymer obtained, while ammonia/lithium acetate two monomeric were crystallized. physicochemical properties, well molecular crystal structure, determined.
