The 1,10-phenanthrolinium cation and 3-hy­droxy-2,4,6-tri­nitro­phenolate anion are held together through an N—H⋯O hydrogen bond. In the crystal, cation–anion pairs are connected by C—H⋯O hydrogen bonds, forming a chain structure along [101]. Spectroscopic data also support the formation of a mol­ecular salt. Sensitivity tests and thermal testing indicate that it is an insensitive high energy density material (IHEDM).

In the crystal of the title mol­ecular salt, the pyridinium cation and the 3-hy­droxy-2,4,6-tri­nitro­phenolate anion are linked through bifurcated N—H⋯(O,O) hydrogen bonds forming an (6) ring motif. Impact, friction sensitivity tests and TGA/DTA studies on this compound imply that it is an insensitive high-energy-density material.

In the title mol­ecule, 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, mol­ecules are linked through weak C—H⋯O hydrogen bonds, forming a two-dimensional network parallel to (001).
