Abstract

Aqua(2-amino-6-methyl pyrimidine-4-ol and leucine)Ni(II) complex was synthesized from nickel chloride hexahydrate (NiCl2·6H2O) with 2-amino-6-methyl pyrimidine-4-ol (HP) as primary ligand and leucine as secondary ligand. The synthesized complex was characterized by elemental analysis, infrared (IR) spectroscopy, ultraviolet-visible (UV-vis) spectroscopy and differential thermal/thermogravimetric analysis (TG/DTA). The prepared complex was subjected to thermal decomposition at 400 °C in an oven which produced pure NiO in the form of regular spherical nanoparticles. The structure of the product was elucidated based on FT-IR, UV, TG/DTA, X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Further, the synthesized nickel oxide nanoparticles demonstrated remarkable antimicrobial activity.
