K. Peters et al., CRYSTAL-STRUCTURE OF DROSERONE IN BIOGENIC CRYSTALS FOUND UNDER THE STEM BARK OF ANCISTROCLADUS-ROBERTSONIORUM, Zeitschrift fur Kristallographie, 210(4), 1995, pp. 290-291
The title compound was detected in a crystalline form under the stem b
ark of Ancistrocladus robertsoniorum when wounded by insects. These ''
biogenic crystals'' belong to the orthorhombic system, space group Pbc
a, with a = 805.0(3) pm, b = 1606.5(6) pm, c = 1410.2(6)pm.
