%X The crystal structure of the title compound, C22H28O5, has been determined by single-crystal X-ray diffraction at 295 K and refined by least squares to a residual of 0.075 (2101 ?observed? reflections). Crystals are triclinic, P&#299;, a 13.789(4), b 11.461(4), c 7.027(3) &#506;, &#945; 81.70(3), &#946; 107.18(2), &#947; 99.10(3)°, Z 2. The structure is shown to be the Z,Z isomer, and its geometry is compared with that of the E,E isomer reported previously.
