Abstract: The title compound, (C₁₀H₉N₂)[Fe(C₇H₃NO₄)₂]·3H₂O, was prepared from the ligand pyridine-2,6-dicarboxylic acid with FeCl₃·6H₂O in the presence of 2,2-bipyridine. The Fe^III atom is six-coordinate in a distorted octahedral geometry. The compound contains protonated 2,2'-bipyridine and doubly deprotonated pyridine-2,6-dicarboxylate (pydc) units; the protonated 2,2'-bipyridine bridges adjacent [Fe(pydc)₂]^- complex units through hydrogen bonding.
