A comparison of the supramolecular structures of 1-(6-amino-1,3-benzodioxol-5-yl)-3-(3,4,5-trimethoxyphenyl)prop-2-en-1-one and 1-(6-amino-1,3-benzodioxol-5-yl)-3-[4-(N,N-dimethylamino)phenyl]prop-2-en-1-one

Abstract: 1-(6-Amino-1,3-benzodioxol-5-yl)-3-(3,4,5-trimethoxyphenyl)prop-2-en-1-one, C₁₉H₁₉NO₆, (I), contains an intramolecular N-HO hydrogen bond and a weak C-HO hydrogen bond, which forms a C(10) chain motif running parallel to the c axis. The 6-amino-1,3-benzodioxol-5-yl moieties are involved in [bold pi] - stacking. 1-(6-Amino-1,3-benzodioxol-5-yl)-3-[4-(N,N-dimethylamino)phenyl]prop-2-en-1-one, C₁₈H₁₈N₂O₃, (II), crystallizes with two molecules in the asymmetric unit. The main feature of the supramolecular structure of (II) is the formation of a centrosymmetric hydrogen-bonded tetramer with an R₈⁴(16) motif.

Formula: C₁₉H₁₉NO₆ and C₁₈H₁₈N₂O₃
