Ferromagnetism at 19K in a bimetallic compound based on 1,2-propanediamine ligand

We report the synthesis, magnetic characteristics and electron paramagnetic resonance (EPR) data on the new hexacyanometallate-based bimetallic molecular compound [Ni(pn) 2 ] 3 . [Fe(CN) 6 ] 2 . 12H 2 O, where pn = 1,2-propanediamine, which shows bulk ferromagnetic order below 19K. It is a soft magn...

Summary:We report the synthesis, magnetic characteristics and electron paramagnetic resonance (EPR) data on the new hexacyanometallate-based bimetallic molecular compound [Ni(pn) 2 ] 3 . [Fe(CN) 6 ] 2 . 12H 2 O, where pn = 1,2-propanediamine, which shows bulk ferromagnetic order below 19K. It is a soft magnet exhibiting a rather weak hysteresis. The EPR spectra show a fine structure, characteristic of an S = 3/2 state, in a very narrow temperature region just above T C that is suggestive of the formation and ordering of S = 3/2 ferromagnetically coupled states of state of Ni 2+ (S = 1) and Fe III (S = 3/2) ions.
