Synthesis, Crystal Structure and Luminescent Properties of One New Ag(I) Complex Based on 3-Aminopyrazine-2-carboxylic Acid
摘要:
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) Å, β=92.7430(10)°, V=1406.70(15) Å3, Z=8. Mr=264.00, Dc=2.493 g/cm3, 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.
