(E)-4,4'-Bis(1,3-benzoxazol-2-yl)stilbene at 150 and 375 K.
The title compound, a chromophore of formula C(28)H(18)N(2)O(2), crystallizes with the molecule lying on an inversion centre to give one-half of a crystallographically independent molecule in the asymmetric unit. The molecule is almost planar, with slight deviation of the benzene rings from the mean molecular plane. The structure is characterized by a herringbone packing arrangement arising from C-H...pi and pi-pi intermolecular interactions. The benzoxazole group is disordered between two orientations, with occupancy factors of 0.669 (10) and 0.331 (10) at 150 K [0.712 (7) and 0.288 (7) at 375 K].
