Reaction between 3,5-pyridinedicarboxylic acid with four different metal salts which are cadmium nitrate tetrahydrate, cobalt acetate, zinc acetate hydrate and nickel chloride produced four novel metal organic frameworks (MOFs), with general formula given by elemental analysis as {(CdLNO3.2H2O)CH3OH}n, {(CoL.2H2O)}n, {(ZnL.2H2O)}n and {(NiL.Cl2))}n (where L=C7H5NO4), respectively. These MOFs were synthesized using solvothermal techniques and fully characterized by using combination of Fourier Transform Infrared (FTIR) and Carbon, Hydrogen, Nitrogen Analyzer (CHN Analyzer). In the FTIR spectra of the MOFs, metal oxide bond peaks were identified at 1393 cm-1, 586 cm-1, 424 cm-1 and 471 cm-1 for Cd-O, Co-O, Zn-O and Ni-O, respectively. Characterization using Ultraviolet-Visible spectroscopy (UV-Vis) was unsuccessful due to limited solubility of MOFs in many solvents.
