A new cyanide-bridged FeIIIMnIII binuclear complex {[Fe(bpy)(CN)4][Mn(TPP)(CH3OH)]}·CH3OH (1) [bpy = 2,2′-bipyridine, TPP = tetraphenylporphyrin] and an ion-pair compound {[Fe(bpy)(CN)4][Mn(TNPP)(CH3OH)2]}·2CH3CN (2) [TNPP = tetra(p-nitrophenyl)porphyrin] have been synthesized based on two manganese(III)-porphyrin precursors [Mn(L)(H2O)2]ClO4 (L = TPP and TNPP) and one cyanide-containing building block K[Fe(bpy)(CN)4]. The crystal structures of the two complexes have been determined by X-ray single crystal diffraction. Magnetic study reveals that complex 1 exhibits weak antiferromagnetic coupling between low-spin Fe(III) and high-spin Mn(III) through the cyanide bridge.
