A novel Ag(I) coordination polymer, [Ag-2(mu-ptmb)(mu(3)-ptmb)] . 2H(2)O (1), (ptmb = 4-(4-pyridylthiomethyl)benzoate), has been synthesized through self-assembly of AgNO3 with Hptmb in CH3CN/H2O mixed solution and characterized by elemental analysis and IR spectra. X-ray diffraction analysis shows that it is a 1D tape-like structure consisting of two kinds of rectangles, which is further hierarchically assembled by Ag...S and S...S weak interactions to form 3D open framework. Luminescence study indicates the complex has an emissive maximum at 500 nm in the solid state at room temperature. (C) 2004 Published by Elsevier B.V.
