In the title compound, [Fe(C5H5)2(C13H11N2O2)], the dihedral angle between the benzene ring and the cyclopentadiene ring bonded to the carbonyl group is 26.1 (2)°. In the crystal, bifurcated O—H
(O,N) and N—HO hydrogen bonds link the molecules into a three-dimensional network.

In title compound, C10H12O4, all of the non-H atoms lie approximately in a plane with the largest deviation being 0.061 (2) Å. An intramolecular O—HO hydrogen bond generates an S(6) ring motif. No classical intermolecular hydrogen bonding occurs, with only van der Waals forces stabilizing the crystal structure.

In the title molecule, C28H18O10, the two central benzene rings form a dihedral angle of 31.0 (1)°. In the phthalic acid fragments, the carboxy groups in the meta positions are approximately coplanar with the attached benzene rings, being inclined to their planes at 2.7 (1) and 10.3 (1)°, while the carboxy groups in the ortho positions are twisted from the benzene ring planes by 83.5 (1) and 75.4 (1)°. In the crystal, O—HO hydrogen bonds link the molecules into layers parallel to the bc plane. Weak C—HO hydrogen bonds and π–π interactions between the aromatic rings [centroid–centroid distance = 3.7674 (3) Å] further consolidate the crystal packing.
