Multi nuclear transition metal complexes have become a central theme of current research because of their potential properties. Synthesis and characterization of polynuclear iron, cobalt, nickel, copper and zinc complexes are reported by many researchers. [1-2] In this report, first we synthesized a new precursor binuclear complex of Zn and Ni of formula [[Ni (phen)(L)(H2O)(μ-SCN)Zn(phen)(L )(OH2)](1) that phen=1-10 phenanthroline, L=Maleate, L = 2-aminobenzoate and then we report facile synthesis of two-phase nanoparticle under thermal decomposition. This complex(1) has been characterized using FT-IR, UV–Vis, Conductivity and Cyclic voltammetry (CV) techniques. Characterization of nano compound from complex (1) was carried out by scanning electron microscopy (SEM), X-ray powder diffraction (XRD) and Fourier transform infrared (FT-IR) spectroscopy. The X-ray diffraction pattern at room temperature revealed, highly pure system Ni-Zn-O with monoclinic structure. Finally nanoparticle has been used as a catalyst in the preparation of tetrahydrobenzo [b] pyran. The FT-IR results showed that the ligands coordinate to metal center as a bidentate ligands by nitrogen and oxygen atoms.
