Abstract

A series of tricyanoiron(III) complexes with the general formula mer-[FeIII(5-Xsap)(CN)3]2− (X = H, Me, MeO, Cl or Br, sapH2 = N-salicylidene-o-aminophenol) have been synthesized. These complexes were characterized by IR, ESI-MS, UV/Vis, elemental analysis and magnetic measurements. The structures of (PPh4)2[FeIII(sap)(CN)3] and (PPh4)2[FeIII(5-Mesap)(CN)3] have been determined by X-ray crystallography. These low-spin d 5 tricyanoiron(III) complexes are potential building blocks for the construction of molecule-based magnets.
