Abstract
The title compound, C22H22O5, crystallizes with two molecules in the asymmetric unit, one of which shows disorder of its ethyl acetate group over two sets of sites in a 0.880 (2):0.120 (2) ratio. The C[triple-bond]C distances in the two molecules are almost the same [1.1939 (16) and 1.199 (2) Å], but the Csp
3—C[triple-bond]C angles differ somewhat [175.92 (12) and 172.53 (16)°]. In the crystal, several weak C—H...O interactions are seen.
