Supramolecular assembly of one-dimensional channels and two-dimensional brick-wall networks from asymmetric dithioether ligands and copper(I) iodide

Two asymmetric dithioether ligands with cyclohexyl (L1) and phenyl (L2) end-groups were synthesized. Reaction of L1 with copper(I) iodide afforded a 1D channel-type coordination polymer {[Cu4I4(L1)2](CH3CN)0.5}n (1) interconnected by cubane-type tetranuclear Cu4I4 cluster units. Whereas, a 2D brick-wall-type coordination polymer [CuI(L2)]n (2) with rhomboid dinuclear Cu–I2–Cu nodes was isolated from the reaction of L2 with copper(I) iodide.
