      plateau.

AB  - A new iron(III) coordination compound exhibiting a two-step spin-transition 
      behavior with a remarkably wide [HS-LS] plateau of about 45 K has been 
      synthesized from a hydrazino Schiff-base ligand with an N,N,O donor set, namely 
      2-methoxy-6-(pyridine-2-ylhydrazonomethyl)phenol (Hmph). The single-crystal X-ray 
      structure of the coordination compound 
      [Fe(mph)(2)](ClO(4))(MeOH)(0.5)(H(2)O)(0.5)(2) (1) determined at 150 K reveals 
      the presence of two slightly different iron(III) centers in pseudo-octahedral 
      environments generated by two deprotonated tridentate mph ligands. The presence 
      of hydrogen bonding interactions, instigated by the well-designed ligand, may 
      justify the occurrence of the abrupt transitions. 1 has been characterized by 
      temperature-dependent magnetic susceptibility measurements, EPR spectroscopy, 
      differential scanning calorimetry, and (57)Fe Mossbauer spectroscopy, which all 
      confirm the occurrence of a two-step transition. In addition, the iron(III) 
      species in the high-spin state has been trapped and characterized by rapid 
      cooling EPR studies.
