4,7-Dimethoxybenzo[c]furan.
The title compound, C10H10O3, is nearly planar with a maximum deviation from planarity of 0.140 (2) A for methoxy atom C11. The geometry of the benzo[c]furan moiety is indicative of a non-aromatic ring system. The bond lengths more closely resemble those of two non-interacting diene systems than those of an aromatic one. There are alternating long and short bond lengths around the ring skeleton with the long and short C-C bonds averaging 1.437 (2) and 1.354 (2) A, respectively. There are close C-H ... O intermolecular contacts which may help stabilize the molecule in the solid state.
