چکیده
In the title compound C(27)H(19)ClO(6), the coumarin ring system is not exactly planar, with a dihedral angle of 4.12 (7)° between its benzene and lactone rings. The cis-fused pyran rings adopt half-chair conformations. The carbometh-oxy and chloro-phenyl groups are in a trans configuration. The crystal packing is stabilized by inter-molecular C-H⋯O interactions, which produce a centrosymmetric R(2) (2)(14) dimer and two centrosymmetric R(2) (2)(18) dimers connecting the mol-ecules in a two-dimensional fashion.

The title compound, C(19)H(14)ClNO(3)·0.2H(2)O, crystallizes with five mol-ecules and a disordered water mol-ecule in the asymmetric unit. Four of the five mol-ecules form hydrogen-bonded dimers via N-H⋯O hydrogen bonds towards another symmetry-independent mol-ecule, whereas the fifth mol-ecule forms a hydrogen-bonded dimer with its symmetry equivalent, also via N-H⋯O hydrogen bonds. The dihedr...
