title: Bis(1,10-phenanthroline-5,6-dione-κN,N')silver(I) 2-hy-droxy-3,5-dinitro-benzoate.
abstract: In the cation of the title salt, [Ag(C(12)H(6)N(2)O(2))(2)](C(7)H(3)N(2)O(7)), the Ag(I) atom is coordinated in a distorted tetra-hedral geometry by four N atoms from two 1,10-phenanthroline-5,6-dione ligands, while the 3,5-dinitro-salicylate anion has only a short contact [2.847 (6) Å] between one of its O atoms and the Ag(I) atom. The dihedral angle between the two 1,10-phenanthroline-5,6-dione ligands is 58.4 (1)°. There is an intra-molecular O-H⋯O hydrogen bond in the 3,5-dinitro-salicylate anion.
