ABSTRACT: A single-crystallow temperature X-ray structure determination of the title compound, C₂₆H₂₈0₄, confirms the stoichiometry, connectivity and stereochemistry recently assigned spectroscopically. Crystals are orthorhombic, ,Pbca, a = 23.65(2), b = 17.58(1), c = 1O.319(6)A, Z = 8 ; the structure was refined to a residual of 0.074 for 485 "observed" independent reflections.
