Abstract
Two supramolecular complexes, {{Ni(H2O)(phen)2[Au(CN)2]}[Au(CN)2] · 1.5H2O} n (1) (phen = 1,10-phenanthroline) and [H2teta][Au2(CN)4] · 2H2O (2) (teta = 5,7,7,12,14,14-hexamethyl-1,4,8,11-tetra-azacyocloteradeca-4,11-diene) have been synthesized and structurally characterized. Complex 1 was a one-dimensional infinite chain constructed by [Au(CN)2]− building blocks. In complex 2, there are one cation, one anion, and two water molecules in the asymmetric unit. The two complexes are interconnected through a combination of aurophilic attractions and hydrogen bonds and formed into 3D supramolecular structures. The aqueous solutions of 1 and 2 display interesting luminescence at room temperature.
