The reaction of Ag 2O with a mixture of benzene-1,3,5-tricarboxylic acid (H 3BTC) and 2-aminopyrazine (APYZ) under the ammoniacal conditions gives rise to a novel metal–organic coordination polymer Ag 6(BTC) 2(APYZ) 6·9H 2O ( 1). The structure of 1 possesses a high ordered lamella 2D structure with an interesting graphite-like 63 net which is comprised of Ag 4 and Ag 6 fused hexagonal rings. 1 exhibits blue photoluminescence at 416 nm ( λ ex = 330 nm) at room temperature which may be mainly ascribed to ligand-to-ligand charge transfer (LLCT). Semiconducting behavior was also measured at ambient temperature with σ values of 5.56 × 10 −7 S cm −1 based on the π–π stacking and Ag(I)–π interactions.

The structure of 1 possesses a high ordered lamella 2D structure with an interesting graphite-like 6 3 net which is comprised of Ag 4 and Ag 6 fused hexagonal rings respectively. 1 exhibits photoluminescence maximized at 416 nm upon 330 nm excitation at room temperature, which may be mainly ascribed to ligand-to-ligand charge transfer (LLCT). Semiconducting behavior was also measured at ambient temperature with σ values of 5.56 × 10 −7 S cm −1 based on the π–π stacking and Ag(I)–π interactions.
