Synthesis and magnetism of multi-dimensional cyanide-bridged bimetallic assemblies

The structures and magnetism of complex-based metal assemblies derived from [M(CN)₆]^n- (M = Cr³⁺, Mn³⁺, Fe³⁺, Co³⁺, Fe²⁺; n = 3, 4) and coordinatively unsaturated [M_A(L)_x]^m+ (M_A = Mn²⁺, Ni²⁺, Cu²⁺, Mn³⁺, Fe³⁺; L = polyamine ligand, salen^2- derivatives) are reviewed. The reaction of the constituents in different ratios, in the absence or presence of an appropriate cation or anion and by the change of ligand L provides multi-dimensional bimetallic assemblies of various networks extended through M-CN-M_A-NC- linkages. The magnetic properties of the assemblies are discussed with respect to their network structures and M_A/M combinations. These assemblies provide significant insights into magnetostructural correlation and design of magnetic materials.
