|Abstract: ||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 19 K. 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 Te that is suggestive of the formation and ordering of S = 3/2 ferromagnetically coupled states of state of Ni2+ (S = 1) and Fe-III (S = 1/2) ions.|
