摘要：
A new cyanide-bridged heterobimetallic Fe(III)-Mn(II) complex {[MnL][FebpdBrb]} [FebpdBrb](n)center dot 2nH(2)O has been synthesized by using pyridinecarboxamide trans-dicyanideiron as the building block. The X-ray diffraction analysis has revealed the one-dimensional infinite structure of the complex consisting of the alternating [Mn(L)](2+) and [Fe(bpdBrb)(CN)(2)](-) units forming a cyanide-bridged cationic polymeric chain, with [Fe(bpdBrb)(CN)(2)](-) as the free anions. The antiferromagnetic coupling between the neighboring Fe(III) and Mn(II) ions through the bridging cyanide group has been revealed. The magnetic coupling constant has been determined as of J = -3.17 cm(-1).
