Abstract

The complete mol-ecule of the title compound, C26H30N4O4, is generated by crystallographic inversion symmetry. The dihedral angle between the planes of the benzene and pyrrole rings is 45.20 (11)°; the N atom bonded to the the benzene ring and the pyrrole N atom are in a syn conformation. The side chain adopts an extended conformation [N-C-C-C = 169.07 (17)° and C-O-C-C = -176.54 (17)°]. No directional inter-actions could be identified in the crystal packing.

Keywords: Schiff base; bis(pyrrole ester); crystal structure.
