Prop-2-ynyl 3-meth-oxy-4-(prop-2-yn-yloxy)benzoate.

The title compound, C 14 H 12 O 4 , comprises of two crystallographically independent mol-ecules in the asymmetric unit, linked via C-H⋯O inter-actions to form dimeric entities. The allylic groups are twisted out of the phenyl planes with dihedral angles varying between 7.92 (13) and 25.42 (8)°. In the crystal, the packing follows a zigzag pattern along the c -axis direction. The absolute configuration of the sample could not be determined reliably.
