The asymmetric unit of the title compound, [Ag(NH3)(2)]-[Ag(C7H5N2O4)(2)], comprises half an [Ag(NH3)(2)](+) cation and half an [Ag(anbz)(2)](-) anion (anbz is 2-amino-5-nitrobenzoate). Both Ag-I ions are located on inversion centres. The cation has a linear coordination geometry with two symmetry-related ammine ligands. The Ag-I cation in the anionic part shows a rare four-coordinate planar geometry completed by two chelating symmetry-related anbz ligands. Intra- and intermolecular N-H center dot center dot center dot O hydrogen bonds create a slightly undulating two-dimensional supramolecular sheet. Adjacent sheets are only ca 3.3 angstrom apart. Ag center dot center dot center dot O, Ag center dot center dot center dot N and pi-pi stacking interactions consolidate the packing of the molecules in the solid state.
