Abstract :
In the title compound [Fe(bpe)(Hbpe)Au(CN)2][Au(CN)2]2·bpe·2H2O}n [where bpe = 1,2-bis(pyridin-4-yl)ethene, C12H10N2], the FeII ion is coordinated in a distorted octahedral [FeN4O2] environment by two dicyanoaurate anions, two water molecules and two partially protonated 1,2-di(4-pyridyl)ethylene molecules. Dicyanoaurate anions bridge the FeII cations, forming infinite chains, which propagate along the a-axis direction. The chains are connected via aurophilic interactions with two non-coordinated dicyanoaurate anions for each FeII ion. The polymeric chains interact with each other via π–π stacking between the guest bpe molecules and multiple hydrogen bonds.
