Crystal structure of poly[tetra-μ-cyanido-ethanol-bis(2-iodo-pyrazine)-digold(I)iron(II)].

ABSTRACT: In the title polymeric complex, [Au₂Fe(CN)₄(C₄H₃IN₂)₂(C₂H₆O)] _n , the Fe^II cation is coordinated by two iodo-pyrazine mol-ecules, one ethanol mol-ecule and three di-cyano-aurate anions in a distorted N₅O octa-hedral geometry. In the crystal, the di-cyano-aurate anions bridge the Fe^II cations to form polymeric chains propagating along the b-axis direction. Stabilization of the crystal structure is provided by O-H⋯N hydrogen bonds and π-π stacking between parallel iodo-pyrazine rings of neighbouring chains, the centroid-centroid distances being 3.654 (10) and 3.658 (9) Å.
