Abstract
The structure and absolute configuration of cardionidine, C21H25O5N, w ere determined by X-ray diffraction analysis. It crystallizes in the s pace group P2(1), with a = 8.499(1) Angstrom, b = 9.494(2) Angstrom, p = 10.918(2) Angstrom, beta = 101.38(2)degrees and D-X = 1.42 g cm(-3) for Z = 2. The molecular structure is based on a heptacyclic skeleton of a C-20 diterpenoid alkaloid of the atisine type, hetisine subtype, featuring an unusual anhydride function. Bond lengths and angles are in the usual range.
