X-ray crystallographic study of ranaconitine.
The crystal structure of natural diterpenoid alkaloid ranaconitine isolated from Aconitum sinomontanum Nakai has been determined by single crystal X-ray diffraction analysis. The crystal presents a monoclinic system, space group C2 with Z = 4, unit cell dimensions a = 30.972(19) angstrom, b = 7.688(5) angstrom, and c = 19.632(12) angstrom. Moreover, the intermolecular O-H...O hydrogen bonds and weak pi-pi interactions play a critical role in expanding the dimensionality.
