4,5-Dichlorophthalic acid-trans-cinnamamide (1/2) and 3,4,5,6-tetrachlorophthalic acid-trans-cinnamamide (1/2)

H. Hosomi, S. Ohba and Y. Ito

Abstract: In the two title adducts, C₈H₄Cl₂O₄·2C₉H₉NO and C₈H₂Cl₄O₄·2C₉H₉NO, respectively, the dicarboxylic acid is connected to two cinnamamide molecules through cyclic hydrogen bonds. The arrangement of the C=C bonds of neighbouring cinnamamide molecules is twisted.

Formula: C₈H₄Cl₂O₄·2C₉H₉NO and C₈H₂Cl₄O₄·2C₉H₉NO
