4-Amino-8-cyclo­pent­yloxy-7-meth­oxy-2H-chromen-2-one monohydrate

The asymmetric unit of the title compound, C₁₅H₁₇NO₄·H₂O, contains two organic mol­ecules with marginal differences between them and two water molecules. The chromine rings in both mol­ecules are essentially planar, with maximum deviations of 0.012 (2) and 0.060 (2) Å. The five-membered cyclo­pentane rings adopt envelope conformations in both mol­ecules. In the crystal, the components are linked by N—H...O, O—H...O and C—H...O hydrogen bonds, resulting in a three-dimensional network.
