The results of magnetic susceptibility, isothermal magnetization, and heat capacity measurements on a newly discovered iron complex with mixed ligands Fe(N 3) 2(4,4 ′-bpy) (4,4 ′-bpy=4,4 ′-bipyridine) are reported. The study of high-temperature magnetic susceptibility data indicates antiferromagnetic correlation of the Fe 2+ moments. However, the results of low-temperature measurements reveals a ferromagnetic transition for this compound, and the Curie temperature is determined from the Arrott plot with T C=20K. The large jump in the heat capacity data confirms the magnetic phase transition and the transition temperature.
