Abstract

Crystals of α- and β-allocryptopine were studied by X-ray diffraction analysis and have been found to be crystal modifications of allocryptopine. They are both monoclinic with <i>a</i> = 18.401(4) Å, <i>b</i> = 7.1590(10) Å, <i>c</i> = 14.084(3) Å, β = 108.98(3)°, <i>P2</i><sub>1</sub>/<i>c</i>, Z = 4, V = 1754.5(6) Å<sup>3</sup> for α-allocryptopine and <i>a</i> = 11.407(2) Å, <i>b</i> = 11.5890(10) Å, <i>c</i> = 14.6673(3) Å, β = 107.82(2)°, <i>P2</i><sub>1</sub>/<i>n</i>, Z = 4, V = 1845.9(5) Å<sup>3</sup> for β-allocryptopine. No major differences in the conformations were found, slight differences are only in the positions of dioxolane rings.
