Synthesis and spectroscopic characterization of Fe3+-BDC metal organic framework as material for lithium ion batteries

•The synthetized mixture of Fe-MOFs were characterized by XRD.•The spectroscopic properties of the Fe-MOFs were investigated by IR.•The electrochemical properties of the Fe-MOFs were investigated by CV, EIS and charge-discharge methods.•The cavities and channels were calculated and used in order to predict the possible accommodation sites for Li+ ions.•The possible interactions of Li+ were described in the structures of Fe-MOFs compounds.
