title: Bis(4-nitro-phen-yl) selenide.
abstract: In the title compound, C12H8N2O4Se, the Se atom is situated on a twofold rotational axis, so the asymmetric unit contains one half-mol-ecule. In the mol-ecule, 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, mol-ecules are held together through weak C-H⋯O inter-actions, forming a three-dimensional network.
