Synthesis and Characterization of a Three-Dimensional Coordination Polymer as Precursor for Preparation of NiO Nanoparticles

A three-dimensional coordination polymer, namely, [Ni( 3 -tp)(μ2 - pyz)]n, ( H2tp = 1,4-benzenedicarboxylic acid (terephthalic acid) and pyz = pyrazine) has been synthesized successfully under hydrothermal conditions and structurally characterized. The polymer shows high thermal stability together with a blue luminescence emission band at 467 nm in the solid state. Thermal decomposition of this polymer as precursor in 600 ᵒC under air atmosphere results in the formation of NiO nanoparticles. The prepared nanoparticles were characterized by scanning electron microscopy (SEM), X-ray powder diffraction (XRD) and IR spectroscopy. This study demonstrates the coordination polymers may be suitable precursors for preparation of nanoscale materials
