title: 6-Meth-oxy-4-methyl-2H-chromen-2-one.
abstract: The whole mol-ecule of the title coumarin derivative, C(11)H(10)O(3), is approximately planar, with a maximum deviation of 0.116 (3) Å from the least-squares plane defined by all non-H atoms. In the crystal, adjacent mol-ecules are linked into chains along [011] via inter-molecular C-H⋯O hydrogen bonds.
