synthesis and optical properties of self-assembled coordination polymer of Zn(ii) ions with phenylmalonic acid and 4-1h-amino- 1,2,4- triazole

Abstract

The coordination chemistry of the phenylmalonic acid and 4-1H- amino- 1,2,4- triazole with Zn(II) ions has been investigated. The coordination polymer was  synthesized by slow evaporation method and characterized by FT-infrared spectroscopy, ultraviolet-visible measurements, scanning electron microscopy, Electron  Dispersive X-ray analysis and Powder X-ray diffraction studies. The ligands and the resulting metal complex gave intense absorption (λ_max = 239 nm) upon irradiation by ultraviolet light, {[Zn₂ (C₉ H₈ O₄ )₂ (C₂ H₄ N₄ )₂ (H₂ O)₄ }n max  (orthorhombic, and P2₁ /cn ) was obtained. An octahedral structure was  proposed for the synthesized Zn(II) complex
