چکیده
The title compound, C(24)H(34)O(6)·2C(3)H(7)NO, which was isolated from fumaric-modified rosin, has four asymmetrically fused six-membered rings and three carboxylic acid substituents. It contains two fused and unbridged cyclo-hexane rings, which form a trans ring junction with a chair conformation. The asymmetric unit includes one fumaropimaric acid and two dimethyl-formamide mol-ecules. The crystal structure is stabilized through inter-molecular O-H⋯O hydrogen bonds between dimethyl-formamide and fumaropimaric acid.
