In the title mol-ecule, C12H6N4O8S2, the dihedral angle between the benzene rings is 77.00 (8)°. The mean planes of the nitro groups are twisted slightly from the benzene rings, forming dihedral angles in the range 2.3 (2)-8.6 (3)°. The S-S bond length is 2.0458 (7) Å. Each S atom is essentially coplanar with the benzene ring to which it is attached, with deviations from the ring planes of 0.0163 (5) and 0.0538 (5) Å. In the crystal, mol-ecules are linked through weak C-H⋯O hydrogen bonds, forming a two-dimensional network parallel to (001).
在标题分子C₁₂H₆N₄O₈S₂中,苯环之间的二面角为77.00 (8)°。硝基的平均平面与苯环略有扭曲,形成的二面角在2.3 (2)-8.6 (3)°范围内。S-S键长为2.0458 (7) Å。每个S原子与其相连的苯环基本共面,与环平面的偏差分别为0.0163 (5)和0.0538 (5) Å。在晶体中,分子通过弱C-H⋯O氢键相连,形成平行于(001)的二维网络。
