Crystal structure of catena-poly[[[di-aqua-[1,2-bis(pyridin-4-yl)ethene]{4-[2-(pyridin-4-yl)ethen-yl]pyridinium}gold(I)iron(II)]-di-?-cyanido] bis-[dicyanido-gold(I)] 1,2-bis-(pyridin-4-yl)ethene dihydrate].

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 octa-hedral [FeN4O2] environment by two di-cyano-aurate anions, two water mol-ecules and two partially protonated 1,2-di(4-pyrid-yl)ethyl-ene mol-ecules. Di-cyano-aurate anions bridge the FeII cations, forming infinite chains, which propagate along the a-axis direction. The chains are connected via aurophilic inter-actions with two non-coordinated di-cyano-aurate anions for each FeII ion. The polymeric chains inter-act with each other via ?-? stacking between the guest bpe mol-ecules and multiple hydrogen bonds.
