In present work, we have synthesized few metal fluoride complexes (CuF2, NiF2, ZnF2) considering 3-aminomethyal pyridine as ligand. We have investigated their physical properties such as decomposition point, molar conductance, infrared and UV-visible spectra. Molar conductance measurements show that the metal fluorides are electrically active materials and support the electrolytic behavior. The infrared spectroscopic analysis exhibits five major bands that attribute to the octahedral geometry describing the strong correlation between fluorides and metal. Moreover, UV-visible exhibits a strong absorption peaks around 650 nm in both Cu and Ni metal complexes. In addition, we have also estimated the energy band gap from UV-visible spectra and found as 1.45 eV and 1.58 eV for Cu-3-AmP and Ni-3-AmP, respectively. Moreover, the observed energy band gap is inconsistent with the obtained values of conductivity. [ABSTRACT FROM AUTHOR]
