The crystal structures of two macrocyclic diterpenoid photoproducts, the chemistry of which has been described in the preceding paper have been determined at 295 K. Compounds I (C20H26O3) and II (C22H30O5) are both orthorhombic, P212121. In I. a = 24.18(1), b = 11.841 c=5.984(2) Å. Z=4. the structure being refined by least squares to a residual of 0.063 for 1234 "observed" reflections. For II. a = 24.30(1), b = 9.413(5). c = 9.149(5) Å. Z = 4 (R = 0.070, 982 "observed" reflections).
