Diethyl 2,2′-({[1,4-phenylenebis(azanediyl)]bis(methylene)}bis(1H-pyrrole-2,1-diyl))diacetate

Abstract

The complete molecule of the title compound, C24H30N4O4, is generated by crystallographic inversion symmetry. The molecule is S-shaped and the pyrrole groups have an anti or trans confirmation with respect to the central benzene ring, to which they are inclined by 76.38 (9)°. In the crystal, molecules are linked via C—H...O hydrogen bonds, forming layers parallel to the ac plane. Within the layers there are C—H...π interactions present. There are, however, no significant interactions between the layers.
