1,1,2,2-Tetra-kis(1,3-benzoxazol-2-yl)ethene

Abstract

The title compound, C 30H 16N 4O 4, 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].
