| Popis: | Cyanide anions bridge FeII and AuI cations to form a one-dimensional polymeric compound with free dicyanoaurate anions. 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 octahedral geometry. It is coordinated by two phenylpyrazine molecules, two water molecules and two dicyanoaurate anions, the Au atom also being located on a second twofold rotation axis. In the crystal, the coordinated dicyanoaurate 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⋯Ndicyanoaurate anions hydrogen bonds and aurophillic interactions [Au⋯Au = 3.5661 (3) Å], forming layers parallel to the bc plane. The layers are linked by offset π–π stacking interactions [intercentroid distance = 3.643 (3) Å], forming a supramolecular metal–organic framework. |
