title: (8S,9S,10R)-4-(4-Chloro-benz-yloxy)-7,8-didehydro-3,7-dimeth-oxy-17-methyl-morphinan-6-one monohydrate.
abstract: In the title compound, C(26)H(28)Cl(N)O(4)·H(2)O, the dihedral angle betwene the two aromatic rings is 69.73 (6)°. The N-containing ring exhibits a chair conformation, while the other non-aromatic rings are in approximate envelope conformations. In the crystal, the water mol-ecule forms O-H⋯O and O-H⋯N hydrogen bonds and a C-H⋯O link also occurs.
