G. J. Halder and C. J. Kepert

Abstract: The title compound, {[Fe(C₁₀H₈N₂)(H₂O)₄](C₈H₄O₄)}_n or [Fe(bpy)(H₂O)₄](bdc) (bpy is 4,4'-bipyridine and bdc is benzene-1,4-dicarboxylate), contains one-dimensional chains of Fe^II centres bridged by bpy ligands along the b axis, with the equatorial coordination of four water molecules completing the octahedral coordination. Non-coordinated bdc anions balance the charge of the Fe^II centres and bridge adjacent one-dimensional chains through an extensive hydrogen-bonding network. The compound crystallizes in the centrosymmetric space group , which defines twofold axes along both the Fe-bpy chains and the bdc anions.
