Abstract—The derivatives of 3-(4-nitrophenyl)-2-phenylacrylic acid are synthesized. It is shown that the
chemical modification of this acid results in a change in the symmetry of the supramolecular fragment formed
by molecules in the crystal. In turn, this change leads to a change in the crystal symmetry and favors the forma-
tion of a noncentrosymmetric crystal structure. The crystal structures of 3-(4-nitrophenyl)-2-phenylacrylic acid
(I), 3-(4-nitrophenyl)-2-phenyl-triethyl aminoacrylate (II), and 3-(4-nitrophenyl)-2-phenylacrylic acid
(3
methoxy)phenyl ester (III) are investigated by X-ray diffraction. © 2003 MAIK “Nauka/Interperiodica”.
