Abstract
The title compound, C30H16N4O4, reveals crystallographic and mol-ecular symmetry and accordingly the asymmetric unit comprises one half-molecule. The dihedral angle between the planes of the two geminal benzoxazole rings is 74.39 (5)°. The packing features weak C - H⋯N and π-π interactions [centroid-centroid distance = 3.652 (1) Å].
