Abstract
New copper(II) complexes [Cu(Pytc)(Cl)2]·2H2O (1) and [Cu2(tzp)2(CH3COO)4] (2) (Pytc = tert-butyl 2-(pyridine-2yl-methylene)hydrazinecarboxylate; tzp = 1,2,3-triazolo[1,5-a]pyridine) were prepared and were characterized by elemental analysis, electron impact mass spectrometry, UV–visible spectroscopy, infrared spectroscopy, and photoluminescence studies. A single-crystal X-ray diffraction study of 2 revealed a paddle-wheel copper(II) acetate structure with tzp acting as a monodentate ligand coordinated axially. Pytc and the metal complexes showed emissive, antibacterial, and antifungal properties. Furthermore, 2 was demonstrated to be a solid-state single-source precursor to form Cu and CuO nanoparticles (NPs) under different atmospheric conditions. By transmission electron microscopy, the as-prepared nanoparticles were observed to be roughly spherical with average particle sizes of approximately 10–12 nm for Cu NPs and approximately 20–22 nm for CuO NPs. Furthermore, high crystallinity, high purity, and the single-phase nature of the as-prepared NPs were revealed by the powder X-ray diffraction pattern.
