| Description | In the binuclear centrosymmetric title compound, [In(2)(C(7)H(3)NO(4))(2)(C(7)H(4)NO(4))(2)(H(2)O)(2)]center dot 4H(2)O, which contains both pyridine-2,3-dicarboxylate and 3-carboxypyridine-2-carboxylate ligands, the In(III) atom is six-coordinated in a distorted octahedral geometry. One pyridine ligand is N,O-chelated while the other is N,O-chelated and at the same time bridging to the other via the second carboxyl group. In the crystal, an extensive O-H center dot center dot center dot O hydrogen-bonding network, involving the coordinated and lattice water molecules and the carboxyl groups of the ligands, together with C-H center dot center dot center dot O and pi-pi interactions [centroid-centroid distance = 3.793 (1) angstrom], leads to the formation of a three-dimensional structure. |
