Summary, etc. By employing two trans-dicyanocobolt(III) building blocks K[Co(bpb)(CN)<sub>2</sub>] (bpb<sup>2-</sup> = 1,2-bis(pyridine-2-carboxamido)benzenate), K[Co(bpmb)(CN)<sub>2</sub>] (bpmb<sup>2-</sup> = 1,2-bis(pyridine-2-carboxamido)-4-methyl-benzenate) and one 14-membered macrocycle Cu(II) compound as assembling segment, two cyanide-bridged Co<sup>III</sup>-Cu<sup>II</sup> complexes {{[Cu(cyclam)][Co(bpb)(CN)<sub>2</sub>]}ClO<sub>4</sub>}<sub>n</sub>·nCH<sub>3</sub>OH·nH<sub>2</sub>O (<strong>1</strong>) and {[Cu(cyclam)][Co(bpmb)(CN)<sub>2</sub>]<sub>2</sub>}·4H<sub>2</sub>O (<strong>2</strong>) (cyclam = 1,4,8,11-tetraazacyclotetradecane) have been successfully prepared and characterized by elemental analysis, IR spectroscopy and X-ray structure determination. Single X-ray diffraction analysis shows that complex <strong>1</strong> can be structurally characterized as one-dimensional cationic single chain consisting of alternating units of [Cu(cyclam)]<sup>2+</sup> and [Co(bpb)(CN)<sub>2</sub>]<sup>-</sup> with free ClO<sub>4</sub><sup>-</sup> as balanced anion, while complex <strong>2</strong> presents cyanide-bridged neutral trinuclear bimetallic structure containing Co<sub>2</sub>Cu core, giving clear information that the substitute group on the cyanide precursor has obvious influence on the structure type of the target compound. Investigation over magnetic properties of complex <strong>1</strong> reveals the weak antiferromagnetic coupling between the neighboring Cu(II) ions through the diamagnetic cyanide building block.
