Bis(4-nitrophenyl) selenide

Abstract: In the title compound, C12H8N2O4Se, the Se atom is situated on a twofold rotational axis, so the asymmetric unit contains one half-molecule. In the molecule, the C-Se-C angle is 99.48 (13)°, the two benzene rings are inclined to each other at an angle of 63.8 (1)° and the nitro group is twisted by 15.9 (1)° from the attached benzene ring. In the crystal, molecules are held together through weak C-H...O interactions, forming a three-dimensional network.
