Two new cyanide-bridged heterobimetallic coordination polymers constructed by using the [Au(CN)2]−building block, {Cd(bipy)[Au(CN)2]2}n(1) and {{Cd(phen)[Au(CN)2]2(H2O)}·iPrOH}n(2) (bipy = 2,2′-bipyridine, phen = 1,10-phenanthroline), have been synthesized and characterized. Complex 1with chiral P3112 space group exhibits a novel three-fold interpenetrating quartz-like 3-D network, which is completely unsupported by aurophilic interactions, while complex 2with the replacement of bipy by phen shows C2/cspace group and features the 1-D zigzag chain structure and an extended supramolecular 2-D array in which aurophilic interactions may play an important role in sustaining the supramolecular solid-state architectures. 1and 2feature various networks most likely due to the different steric hindrances of the bipy and phen ligands. In addition, the solid state photoluminescence spectrum of complex 2exhibits a strong green emission band (λmax= 524 nm) at room temperature. [ABSTRACT FROM AUTHOR]
