The structure of the jatrophane diterpenoid (ES2), CHO, has ortho-rhom-bic (222) symmetry. The absolute configuration in the crystal has been determined as 2,3,4,5,7,8,9,13,14,15 [the Flack parameter is -0.06 (11)]. The mol-ecular structure features intra-molecular O-H⋯O and C-H⋯O hydrogen bonding. In the crystal, C-H⋯O hydrogen bonds link the mol-ecules into supra-molecular columns parallel to the axis. One of the acet-oxy substituents is disordered over two orientations in a 0.826 (8):0.174 (8) ratio.

Crystal growth of 2-(3,4,5-triphen-ylphen-yl)acetic acid () from aceto-nitrile yields a monosolvate, CHO·CHCN, of the space group 1. In the crystal, the title mol-ecule adopts a conformation in which the three phenyl rings are arranged in a paddlewheel-like fashion around the central arene ring and the carboxyl residue is oriented nearly perpendicular to the plane of this benzene ring. Inversion-symmetric dimers of O-H⋯O-bonded mol-ecules of represent the basic supra-molecular entities of the crystal structure.
