N,N′-(2-Hy­droxy­propane-1,3-di­yl)bis­(2-hy­droxy­benzamide) monohydrate

In the title hydrate, C₁₇H₁₈N₂O₅·H₂O, the complete organic mol­ecule is generated by a crystallographic mirror plane with one C and one O atom lying on the mirror plane. The O atom of the water mol­ecule has m site symmetry. Two symmetry-related intra­molecular O—H...O hydrogen bonds complete S(6) rings in the organic mol­ecule. In the crystal, the components are linked into (010) sheets by O—H...O and N—H...O hydrogen bonds.
