Crystal structure of 4-meth-oxy-phenyl 2-oxo-2H-chromene-3-carboxyl-ate.


ABSTRACT: In the title compound, C17H12O5, the dihedral angle between the planes of the coumarin ring system (r.m.s. deviation = 0.015?Å) and the benzene ring is 48.04?(10)°. The central CO2 group subtends a dihedral angle of 27.15?(11)° with the coumarin ring system and 74.86?(13)° with the benzene ring. In the crystal, mol-ecules are linked by C-H?O inter-actions, which generate a three-dimensional network. Very weak C-H?? inter-actions are also observed.
