Abstract

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 1 with chiral P3112 space group exhibits a novel three-fold interpenetrating quartz-like 3-D network, which is completely unsupported by aurophilic interactions, while complex 2 with the replacement of bipy by phen shows C2/c space 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. 1 and 2 feature 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 2 exhibits a strong green emission band (λmax = 524 nm) at room temperature.
