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

Area of Science:

• Coordination Chemistry
• Supramolecular Chemistry
• Crystallography

Background:

• Silver(I) coordination compounds with nitrogen-rich ligands are of interest for their structural diversity.
• Melamine (1,3,5-triazine-2,4,6-triamine) is a versatile ligand capable of forming extensive hydrogen bond networks.

Purpose of the Study:

• To synthesize and characterize a novel silver(I) coordination compound with melamine.
• To elucidate the crystal structure and supramolecular assembly of the title compound, [Ag(melamine)(2)]NO(3).

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
• Analysis of hydrogen bonding and pi-pi interactions was performed to understand structural stabilization.

Main Results:

• The compound exhibits an alternating two-dimensional bilayer structure.
• Cationic [Ag(melamine)(2)](+) monomers form 2D sheets via N-H...N hydrogen bonds.
• Nitrate anions are intercalated between the sheets through N-H...O hydrogen bonds.
• Ag(I) ions display near-linear coordination geometry.
• Melamine ligands show slight distortion attributed to pi-pi interactions.

Conclusions:

• The study successfully characterized a novel 2D bilayer silver-melamine coordination compound.
• Extensive hydrogen bonding and pi-pi interactions are crucial for the observed supramolecular architecture.
• The findings contribute to the understanding of silver coordination chemistry and the self-assembly of functional materials.
