The compound was characterized by UV-vis, NMR and X-ray single-crystal structure analysis. It crystallizes in triclinic space group P1 with a = 10.2251（5）, b = 10.6014（5）, c = 15.7012（5） A, α = 92.963（3）, β = 92.641（3）, γ = 114.647（4）°, V = 1540.6（1）A 3, Z = 2, Mr = 676.24, Dc = 1.458 g/cm3, F（000） = 688, μ = 6.187 mm^-1, GOOF = 1.038, the final R = 0.0530 and wR = 0.1493 for 6371 observed reflections with I 〉 2σ（I）. Compound 1 is ionic. It is composed of a BF4- anion and a [Ag（Mepzpy）（PAr3）]＋ cation. The Ag（I） ion adopts a distorted trigonal pyramidal coordination geometry defined by two nitrogen atoms and a phosphorous atom. The complex emits blue luminescence with maximum peaks at 470 nm in solid state at room temperature.展开更多
