The title compound, C(24)H(32)O(5)·C(2)H(4)O(2), is a derivative of abietic acid. The two fused and unbridged cyclo-hexane rings have chair conformations and the anhydride ring is planar. Of the other three six-membered rings, two have boat conformations and one has a twist-boat conformation. The crystal structure is stabilized by inter-molecular O-H⋯O and C-H⋯O hydrogen bonds.
标题化合物C(24)H(32)O(5)·C(2)H(4)O(2)是枞酸的衍生物。两个稠合且无桥连的环己烷环呈椅式构象,酸酐环为平面结构。在另外三个六元环中,两个呈船式构象,一个呈扭船式构象。晶体结构通过分子间的O-H⋯O和C-H⋯O氢键得以稳定。
