Synthesis, structure and luminescent property of a 2D polymer containing silver ions

Silver(I) complex with 4,5-dicarboxyimidazole (H3dcbi) has been synthesized by hydrothermal method and proven to be a novel 2D coordination polymer [Ag(H2dcbi)]n (1), which crystallized in monoclinic crystal system and space group of P2(1)/c. Each Ag(I) ion is coordinated to three O atoms and one N atom, which completes the trigonal pyramidal geometry of Ag(I) ion. Solid-state fluorescent emission spectra of 1 were investigated.
