title: 1,1,2,2-Tetra-kis(1,3-benzoxazol-2-yl)ethene.
abstract: The title compound, C(30)H(16)N(4)O(4), reveals [Formula: see text] crystallographic and mol-ecular symmetry and accordingly the asymmetric unit comprises one half-mol-ecule. 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 inter-actions [centroid-centroid distance = 3.652 (1) Å].
