For 1 and 2, as the substituents change from H to methyl, the dimensions of 1-2 decrease from three-dimension (3D) to one-dimension (ID) due to the steric effect of methyl groups. For 3 and 4, as the ratios of Ag2O/apyz/pma vary from 1:1:1 to 2:1:1. the structure of 3 is a 1D ladder structure built from Ag-apyz double chains and pma anions, while the structure of 4 is a two-dimension (2D) grid. As excess ammonia is added to above four reaction systems, the structure of 5 contains unprecedented {[Ag(NH3)(2)](+)}(n) chains and pma anions. The substituent on the pyrimidyl ring, ratios of reactants, solvent systems and ligand isomers intensively influence the coordination environments of metal ion and the coordination modes of the carboxyl group, and thus determine the structures of the coordination polymers. The photoluminescent properties of 1-5 were also investigated. (C) 2010 Elsevier Ltd. All rights reserved.; National Natural Science Foundation of China 20721001 MSTC 2007CB815301
