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 Ag-3(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 (lambda(ex) = 383 nm) and upon cooling to 77 K, the emission spectrum seems narrowly red-shifted.
