Abstract

A new 3D silver complex [Ag(mela)(H2O)(NO3)]n (1) (mela = melamine or 2,4,6-triaminotriazine) is synthesized and characterized by single crystal X-ray diffraction, IR, and elemental analysis. The structural characterization shows that the compound crystallizes in space group C c, a = 8.181(2), b = 10.269(3) c = 11.347(3) Å, β = 105.88(2)°, Z = 4. Out of several structurally characterized transition metal compounds comprising melamine, the titled complex represents a rare example of μ3-melamine coordination mode realized through the heterocycle nitrogen donors. The fluorescent property of complex 1 was investigated and the mechanism was validated by means of a density functional theory (DFT) calculation.

Graphical Abstract

A new 3D silver complex was synthesized using the 2,4,6-triaminotriazine ligand. The X-ray structural analysis shows a highly distorted trigonal bipyramidal geometry of Ag(I) ion with a rare μ3-coordination mode of the ligand achieved through the heterocyclic nitrogen donors. Emission study reveals intraligand and ligand-to-metal charge transfer in the complex.
