Abstract:
The asymmetric unit of the title compound, C(15)H(17)NO(4)·H(2)O, contains two organic mol-ecules with marginal differences between them and two water molecules. The chromine rings in both mol-ecules are essentially planar, with maximum deviations of 0.012 (2) and 0.060 (2) Å. The five-membered cyclo-pentane rings adopt envelope conformations in both mol-ecules. 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.
