description | In the title compound, alternatively called α-hydroxy-γ-alkylidenebutenolide, C(12)H(16)O(3), two independent molecules (A and B) crystallize in the asymmetric unit in each of which the 5,6-dihydrobenzo ring has an envelope conformation. The torsion angle along the butadiene chain in the γ-alkylidenebutenolide core is −177.9 (2)° for molecule A and 179.9 (2)° for molecule B. In the crystal, O—H⋯O hydrogen bonds between hydroxyl and carbonyl groups of adjacent independent molecules form dimers with R (2) (2)(10) loops. |
