Bis(1,3,5-triazine-2,4,6-triamine-κN1)silver(I) nitrate

The title compound, [Ag(C3H6N6)(2)]NO3, 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 center dot center dot center dot N hydrogen bonds to form two-dimensional sheets. Nitrate groups are sandwiched between two sheets through N-H center dot center dot center dot 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.
