Abstract

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)₈^3- 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 (J_p = 3.88 cm^-1). Interunit ferromagnetic interactions (J_c = -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.
