The title compound, C(16)H(10)N(2)O(6).2H(2)O, crystallized in the centrosymmetric triclinic space group P-1 with one organic molecule and two water molecules as the asymmetric unit. Eight intermolecular hydrogen bonds have donor.acceptor distances in the range 2.602 (2)-3.289 (2) A, with angles in the range 137 (2)-177 (2) degrees. These generate a three-dimensional hydrogen-bond network. There is a single intramolecular hydrogen bond. There are six significant intermolecular C-H.O interactions with H.O distances in the range 2. 39-2.74 A, and C-H.O angles in the range 131-157 degrees.
