چکیده
In the title compound, C(11)H(10)O(3), the benzodioxole ring adopts a flattened [puckering parameters: q(2) = 0.107 (2) Å, ϕ(2) = 160 (1)°] envelope conformation with the methylene C atom as the flap. The crystal packing features chains, parallel to the c axis, composed of dimers connected by weak C-H-O hydrogen bonds and extending in layers in the bc plane.
