Synthesis, Crystal Structure and Luminescent Properties of One New Ag(I) Complex Based on 3-Aminopyrazine-2-Carboxylic Acid

One new AgI complex, [Ag(apca)(H2O)]n(Hapca = 3-aminopyrazine-2-carboxylic acid), has been prepared and structurally and spectroscopically characterized. The title complex(1) crystallizes in the monoclinic system P21/c(No. 14) with a = 14.3307(9), b = 14.9296(9), c = 6.5824(4) ?, β = 92.7430(10)o, V = 1406.70(15) ?3, Z = 8. M3r = 264.00, Dc = 2.493 g/cm, μ = 2.831 mm-1, F(000) = 1024, the final R = 0.0266 and wR = 0.0788 for 3107 observed reflections with I > 2σ(I). Its structure features a three-dimensional(3D) network composed of one-dimensional(1D) [Ag(apca)(H2O)]n ribbons interconnected via weak hydrogen bonds and π-π interactions. Emission spectra of the title complex in the solid state at room temperature give strong green luminescence.
