Two new silver(I) coordination polymers (CPs) of the formula [Ag-2(dmapym)(4)(mal)center dot H2O](n) (1) and [Ag-3(apym)(3)(mal)NO3](n) (2) (dmapym = 2-amino-4,6-dimethylprimidine, apym = 2-aminopyrimidine, H(2)mal = malonate) have been synthesized by reactions of AgNO3 and 2-aminopyrimidyl ligands with malonate under the ammoniacal condition. Both complexes have been characterized by element analysis, IR and single-crystal X-ray diffraction. The monodentate dmapym and tridentate mal ligands link Ag(I) ions to give complex 1 a one-dimensional (1D) H-shaped chain structure. The complex 2 is a two-dimensional (2D) double sheet structure constructed by (4,4) single sheet. Additionally, the hydrogen-bonding and C-H center dot center dot center dot pi interactions also direct the self-assembly of supramolecular architectures. The photoluminescence properties of the 1 and 2 were investigated in the solid state at room temperature. (C) 2010 Elsevier B.V. All rights reserved.
