Crystal structure and Hirshfeld surface analysis of the naturally occurring cassane-type diterpenoid, 6β-cinnamoyl-7β-hy­droxy­vouacapen-5α-ol

The title compound, C(29)H(36)O(5), a cassane-type diterpenoid {systematic name: (4aR,5R,6R,6aS,7R,11aS,11bR)-4a,6-dihy­droxy-4,4,7,11b-tetra­methyl-1,2,3,4,4a,5,6,6a,7,11,11a,11b-dodeca­hydro­phenanthro[3,2-b]furan-5-yl 3-phenyl­prop-2-enoate}, was isolated from a medicinally important plant, Caesalpinia pulcherrima (Fabaceae). In the mol­ecule, three cyclo­hexane rings are trans-fused and adopt chair, chair and half-chair conformations. In the crystal, mol­ecules are linked via O—H⋯O hydrogen bonds, forming a tape structure along the b-axis direction. The tapes are further linked into a double-tape structure through C—H⋯π inter­actions. The Hirshfeld surface analysis indicates that the contributions to the crystal packing are H⋯H (65.5%), C⋯H (18.7%), O⋯H (14.5%) and C⋯O (0.3%).
