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

ABSTRACT: In the title polymeric complex, {[Fe(CN)2(C10H8N2)2(H2O)2][Au(CN)2]} n , the FeII 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 FeII ions to form polymeric chains propagating along the b-axis direction. In the crystal, the chains are linked by Owater-H?Ndi-cyano-aurate anions hydrogen bonds and aurophillic inter-actions [Au?Au = 3.5661?(3)?Å], forming layers parallel to the bc plane. The layers are linked by offset ?-? stacking inter-actions [inter-centroid distance = 3.643?(3)?Å], forming a supra-molecular metal-organic framework.
