title: Methyl 2-oxo-2H-chromene-3-carboxyl-ate.
abstract: The title compound, C(11)H(8)O(4), features an almost planar mol-ecule (r.m.s. deviation = 0.033 Å for all non-H atoms). In the crystal, the mol-ecules are linked via C-H⋯O hydrogen bonds, forming two-dimensional networks lying parallel to (1-21).
