Abstract
In the title compound, C28H21ClN4O4, the benzofuran ring systems make dihedral angles of 7.43 (8) and 30.92 (9)° with the chloro-substituted benzene ring. The dihedral angle between the two benzofuran ring systems is 27.41 (7)°. The two benzofuran rings are connected to the chloro-substituted benzene ring through C—N—N=C and C—N—N=C—C bridges which are nearly planar [maximum deviations = 0.003 (1) and 0.037 (1) Å]. An intramolecular N—H⋯N hydrogen bond generates an S(6) ring motif. In the crystal, molecules are linked by N—H⋯(O,N) and C—H⋯O hydrogen bonds into a tape along the c axis and these tapes are further connected by another weak C—H⋯O hydrogen bond into a sheet parallel to the bc plane. π–π interactions [centroid-to-centroid distances = 3.4845 (12)–3.6250 (13) Å] are also observed.
