Abstract A cyanide-bridged CrIIICoII bimetallic complex [Cr(bpb)(CN)2Co(LN5)·2H2O·ClO4]n (bpb2− = 1,2-bis(pyridine-2-carboxamido)benzenate, LN5 = 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 [CoII(LN5)(H2O)2](ClO4)2 with the trans-dicyanidechromate(III) building block K[CrIII(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 TN = 9.4 K. The typical metamagnet behaviors were observed with the critical field of ca. 2.6 kOe at 2.0 K.
