Solution phase reaction of AgNO3 with a mixture of benzene-1,3,5-tricarboxylic acid (H3BTC) and heterocyclic 2-aminopyrimidine (APYM) under the ammoniacal conditions gives rise to a novel metal–organic coordination polymer Ag3(BTC)(APYM)2 (1). The structure of 1 possesses a unique three-dimensional (3D) framework with one-dimensional channels surrounded by carboxylato-supported Ag–Ag dimers, Ag–Ag chains, fully deprotonated [BTC]3− and APYM ligands. Moreover, 1 exhibits strong blue photoluminescence maximized at 464 nm at room temperature (λex = 383 nm) and upon cooling to 77 K, the emission spectrum seems narrowly red-shifted.

Furthermore, this metal–organic polymer exhibits strong blue photoluminescence maximized at 464 nm upon 383 nm excitation at room temperature.
