A new one-dimensional cyanide-bridged Cr-III-Mn-III complex [Cr(bpb)(CN)(2)][Mn(bpb)]center dot 2CH(3)OH [bpb(2-) = 1,2-bis(pyridine-2-carboxamido)benzenate] (1) has been synthesized by the reaction of [Mn(bpb)(H2O)(2)]ClO4 and K[Cr(bpb)(CN)(2)]. The single-crystal X-ray diffraction analysis shows that the structure of complex 1 is a one-dimensional coordination polymer type with two different metal centers which is alternated linked by cyanide group from the K[Cr(bpb)(CN)(2)] building blocks. Magnetic investigations reveal that the magnetic interaction between Cr(III) and high-spin Mn(III) ions through the cyanide bridge is weak antiferromagnetic coupling.
