3D Coordination Network of Ag(I) Ions with μ 3 -Bridging Melamine Ligands

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\ud group C c, a = 8.181(2), b = 10.269(3) c = 11.347(3) A ° , b = 105.88(2) A, Z = 4. Out of several structurally characterized transition metal compounds comprising melamine, the titled complex represents a rare example of l3-melamine coordination mode realized through the heterocycle nitrogen donors. The fluorescent property of complex 1 was investigated and the mechanism was validated\ud by means of a density functional theory (DFT) calculation
