A new type of one-dimensional cyanide-bridged Cu(II)-Mo(V) bimetallic assembly, [Cu(cyclam)]3[Mo(CN)8]2· 5H2O (cyclam = 1,4,8,11-tetraazacyclotetradecane), was prepared by self-assembling Mo(CN)83- and Cu(cyclam)2+ ions in a 2:3 stoichiometric ratio. The overall molecular view is delineated as a novel rope-ladder chain structure. It displays a dominant ferromagnetic behavior within a pentanuclear Cu3Mo2 unit (Jp = 3.88 cm-1). Interunit ferromagnetic interactions (Jc = -0.03 cm-1) through a longer magnetic pathway of Cu-Mo and weak antiferromagnetic couplings (zJ′ = -0.46 cm-1) resulting from interchain interactions are obtained.
