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.
标题化合物[Ag(C₃H₆N₆)₂]NO₃具有由广泛氢键支撑的交替二维双层结构。[Ag(三聚氰胺)₂]⁺阳离子单体（三聚氰胺为1,3,5-三嗪-2,4,6-三胺）通过N-H...N氢键相连形成二维片层。硝酸根离子通过N-H...O氢键夹在两片层之间。发现Ag(I)离子具有几乎完美的线性配位几何构型。由于π-π相互作用，三嗪配体略有扭曲。
