چکیده
The spectroscopic studies of transition metal complexes of iron. metal complexes, are characterized by XRD, FTIR, H NMR, Mössbauer and VSM (vibrating sample magnetometer) measurements, are reported in the present paper. The XRD analysis reveals the crystalline nature of all the compounds. Mössbauer study interprets paramagnetic nature of complexes at room temperature. VSM measurements also reveal the paramagnetic nature of complexes at higher temperature range, while complexes follow magnetic phase transition from paramagnetic to anti-ferromagnetic nature at low temperature.
