Crystal structure of catena-poly[[gold(I)-μ-cyanido-[di-aqua-bis-(2-phenyl-pyrazine)-iron(II)]-μ-cyanido] dicyanidogold(I)].

ABSTRACT: In the title polymeric complex, {[Fe(CN)₂(C₁₀H₈N₂)₂(H₂O)₂][Au(CN)₂]} _n , the Fe^II ion, which is located on a twofold rotation axis, has a slightly distorted FeN₄O₂ octa-hedral geometry. It is coordinated by two phenyl-pyrazine mol-ecules, two water mol-ecules and two di-cyano-aurate anions, the Au atom also being located on a second twofold rotation axis. In the crystal, the coordinated di-cyano-aurate anions bridge the Fe^II ions to form polymeric chains propagating along the b-axis direction. In the crystal, the chains are linked by O_water-H⋯N_{di-cyano-aurate anions} hydrogen bonds and aurophillic inter-actions [Au
