Crystal Structure of Rabdoternin A.

Rabdoternin A is a natural diterpenoid isolated from Rabdosia rubescen and its crystal structure was determined by X-ray single crystal diffraction. The compound compactly packs in an orthorhombic unit cell in the P222 space group with unit cell dimensions a = 7.9200(10) Å, b = 11.2411(14) Å, c = 20.474(2) Å, V = 1822.8(4) Å and Z = 4. Two intermolecular hydrogen bonds assemble the title compound into infinite two-dimensional networks along (001) plane. Graphical Abstract: Rabdoternin A is a natural diterpenoid isolated from Rabdosia rubescen and its crystal structure was determined by X-ray single crystal diffraction. The compound is built up from five-six-membered rings and one-five-membered ring, intermolecular hydrogen bonds assemble the title compound into infinite two-dimensional networks along (001) plane.[Figure not available: see fulltext.] [ABSTRACT FROM AUTHOR]
