A cyanide-bridged (CrCoII)-Co-III bimetallic complex [Cr(bpb)(CN)(2)Co(L-N5)center dot 2H(2)O center dot ClO4](n) (bpb(2) = 1,2-bis(pyridine-2-carboxamido) benzenate, L-N5 = 2,13-dimethyl-3,6,9,12,18-pentaazabicyclo[12.3.1] octadeca-1 (18), 2,12,14,16-pentaene) (1) has been synthesized by the reaction of [Co-II(L-N5)(H2O)(2)](ClO4)(2) with the trans-dicyanidechromate(III) building block K[Cr-III(bpb)(CN)(2)]. X-ray single crystal diffraction analysis shows that complex 1 exhibits a cyanide-bridged Cr(III) and Co(II) alternating one-dimensional (1D) wave-like structure. Magnetic investigations show that complex 1 displays over all ferromagnetic coupling between Cr(III) and Co(II) through cyanide bridge with long-range antiferromagnetic ordering of T-N = 9.4 K. The typical metamagnet behaviors were observed with the critical field of ca. 2.6 kOe at 2.0 K.
