Abstract
In the crystalline state, the centrosymmetric molecule 1,2,4,5-tetrakis(cyanomethyl)benzene, C14H10N4, has one cyanomethyl group in the benzene plane and one cyanomethyl group rotated 67.2 (2)° out of the benzene plane. Molecules of methyl 3,4,5-triacetoxybenzoate, C14H14O8, form chains with each molecule twisted \pm89.6 (1)° from the preceding molecule. In this orientation, a close C—H⋯O contact is formed, with an H⋯O distance of 2.34 A. The structure of 2-(N-phthalimidomethyl)benzoic acid, C16H11NO4, reveals hydrogen-bonded dimers linked by the carboxyl groups of adjacent molecules. The O4⋯O3 distance is 2.636 (2) A and the O4—H⋯O3 angle is 171 (2)°.
