Synthesis, crystal structure and characterization of new tetranuclear Ag(I) complex with 5-aminoisophthalate

One new AgI complex, [Ag2(aip)(NH3)]n (H2aip = 5-aminoisophthalic acid), has been prepared and structurally and spectroscopically characterized. The title complex crystallizes in the monoclinic system P21/c (no. 14) with a = 6.975(2) Å, b = 8.756(3) Å, c = 16.086(6) Å, β = 97.318(4)°, V = 974.4(6) Å3 and Z = 4. Its structure features a three-dimensional (3D) network composed of two-dimensional (2D) flexuous layer interconnected via weak hydrogen bonds. In aqueous solution, the H2aip exhibits blue emission, while the title complex with tetranuclear silver(I) cores and weak Ag…Ag bonds shows visible intense purple luminescence.

One new silver(I) complex [Ag2(aip)(NH3)]n has been synthesized and structurally characterized. The complex features 3D network built from 2D flexuous layer containing tetranuclear silver(I) core. In the aqueous solution state, the H2aip can give strong blue emission, whereas the complex 1 exhibits strong purple luminescence at room temperature.Figure optionsDownload as PowerPoint slideHighlights
