The title compound, [Ag(C(3)H(6)N(6))(2)]NO(3), has an alternating two-dimensional bilayer structure supported by extensive hydrogen bonds. The [Ag(melamine)(2)](+) cationic monomers (melamine is 1,3,5-triazine-2,4,6-triamine) are connected via N-H...N hydrogen bonds to form two-dimensional sheets. Nitrate groups are sandwiched between two sheets through N-H...O hydrogen bonds. An almost perfectly linear coordination geometry is found for the Ag(I) ions. The triazine ligands are slightly distorted due to pi-pi interactions.
