Abstract

In the title compound, C28H20N2O10·CHCl3, the phen­oxy rings are inclined to the central phenyl ring at dihedral angles of 84.71 (13) and 80.56 (13)°. In the crystal, pairs of weak inter­molecular C—H⋯O hydrogen bonds link mol­ecules related by an inversion center, forming dimers. There are also C—H⋯π inter­actions present.
