B. Tashkhodzhaev et al., CRYSTAL AND MOLECULAR-STRUCTURE OF THE HYDROCHLORIDE OF THE DITERPENEALKALOID HETISINE, Journal of inclusion phenomena and molecular recognition in chemistry, 14(3-4), 1993, pp. 311-316
The molecular and crystal structure of hetisine hydrochloride has been
obtained and compared with those of the hydrobromide and perchlorate
salts. These structures have been investigated as coordinatoclathrates
and it has been shown that on changing from chloride to bromide and t
hen to perchlorate a morphotropic transition is observed.
