S. M. Witko, M. Davison, H. W. Thompson and R. A. Lalancette

Abstract: In the title crystal structure, C₉H₁₄O₃·H₂O, the water molecule accepts a hydrogen bond from the carboxyl group [OO = 2.6004 (13) Å and O-HO = 163°], while donating hydrogen bonds to the ketone [OO = 2.8193 (14) Å and O-HO = 178 (2)°] and the acid carbonyl groups [OO = 2.8010 (14) Å and O-HO = 174 (2)°]. This creates a network of hydrogen bonds confined within a continuous flat ribbon two molecules in width and extending in the [101] direction.
