摘要：
The crystal structure of the C-20 diterpenoid alkaloid 6,9-dihydroxy-2-oxohetisan-13-yl acetate consists of two independent molecules in the asymmetric unit with average bond distances C(sp3)-C(sp3) 1.55 (1), C(sp3)-C(sp2) 1.52 (1), C=C 1.31 (1), N-C 1.51 (1), C(sp3)-O 1.46 (1), C(Sp2)-O 1.35 (1) and C=O 1.22 (1) angstrom. The structure is stabilized through a network of hydrogen bonds involving nitrogen and hydroxy groups with O ... O and O ... N separations in the range 2.688 (7)-2.903 (8) angstrom.
