N,N'-Dihydroxybenzene-1,2:4,5-tetracarboximide dihydrate

R. Centore and A. Carella

Abstract: In the title compound, C10H4N2O6·2H2O, the organic molecule has crystallographically imposed inversion symmetry. The atoms of the three fused rings of the molecule are coplanar within 0.0246 (8) Å, while the two hydroxy O atoms are displaced from the mean plane of the molecule by 0.127 (1) Å. In the crystal, infinite near-planar layers of close-packed molecules are formed by hydrogen bonding between water O-H donor groups and carbonyl O-atom acceptors, and by weak interactions between C-H donor groups and water O-atom acceptors. The layers are parallel to the {102} family of planes. The stacked planes are held together by hydrogen bonding between N-OH donor groups and water O-atom acceptors.
