Abstract

The crystal and molecular structure of a grayanotoxin derivative, iso-grayanotoxin II, is presented. The crystal is orthorhombic, space group \(P2_1 2_1 2_1 ,{\text{ with }}a{\text{ = 12}}{\text{.357(1) }}{\AA}{\text{, }}b{\text{ = 23}}{\text{.354(1) }}{\AA}{\text{, }}c = 6.284(2){\text{ }}{\AA}{\text{, }}V = 1813.3(6)\,{\AA}^3 {\text{, }}Z = 4 \) . The molecule is based on a tetracyclic structure consisting of two five-membered, one six-membered, and one seven-membered rings with various conformations.
