N2  - The crystal structure of the title compound, C18H18O5, has been determined by single-crystal X-ray diffraction methods at 295 K and refined by least squares to a residual of 0.058 for 1502 'observed' reflections. Crystals are monoclinic, P 21/n, a 22.048(6), b 7.075(2), c 10.443(3) &#506;, &#946; 100.40(3)&#176;, Z 4.     The structure was solved by a combination of special direct phasing procedures and translation functions, after conventional direct methods had failed.
