Hexamethylenetetramine and rac-trans-1,2-cyclohexanedicarboxylic acid crystallize in a 1:1 ratio as a neutral molecular adduct, C6H12N4.C8H12O4. Two dicarboxylic acid molecules and two tetramine molecules form a hydrogen-bonded ring, in the shape of a rhombus, which lies on a crystallographic twofold axis bisecting the two diacid molecules. The O-H...N hydrogen bonds have lengths 2.6808 (19) and 2.6518 (19) A, and, in each ring, both acid molecules have the same handedness.
六亚甲基四胺与外消旋反式-1,2-环己烷二甲酸以1:1的比例结晶形成中性分子加合物C₆H₁₂N₄·C₈H₁₂O₄。两个二元羧酸分子和两个四胺分子形成一个氢键连接的菱形环，该环位于平分两个二酸分子的晶体学二重轴上。O—H…N氢键长度为2.6808 (19) Å和2.6518 (19) Å，并且在每个环中，两个酸分子具有相同的手性。
