Synthesis, crystal structures and luminescent properties of two supramolecular assemblies containing [Au(CN)2]− building block†
Abstract
Two self-assembled supramolecular architectures {{MnH2O(Phen)2[Au(CN)2]}[Au(CN)2]·0.5C2H5OH·0.5H2O}n (phen = 1, 10-phenanthroline) (1) and [C6H13N4][Au(CN)2]·H2O(C6H13N4 = 4-amide-3, 5-diethyl-1, 2, 4-triazole cation) (2) have been synthesized and structurally characterized. X-ray crystallography revealed a three-dimensional structure of 1 formed by the incorporation of coordinative linkage, aurophilic, hydrogen-bonding and π–π interactions. The 2D structure of 2 is formed by aurophilic and hydrogen-bonding interactions. Both the solid phases and aqueous solutions of 1 and 2 display interesting luminescence at room temperature.
