摘要：

Three Ag(I) coordination complexes, [Ag(pyzca)](n) (1) (Hpyzca = pyrazine-2-carboxylic acid), Ag[(HNA)(NA)(H2O)(4)] (2) (HNA = nicotinic acid) and [(AgAg2)-Ag-1-(2,3-pydc)](n) (3) (H(2)pydc = pyridine-2, 3-dicarboxylic acid) have been synthesized by the hydrothermal method. Their structures are determined by single-crystal X-ray diffractometer. Complex 1 possesses the 3D infinite structure. Complex 2 is a mononuclear coordination complex and exhibits one 3D infinite network by a large number of hydrogen bonds. In complex 3, two crystallographic independent Ag(I) ions exist, i.e., Ag-1 is three-coordinate and Ag-2 is two-coordinate, forming the 2D layer structure. At room temperature in the solid state, the IR, FP and UV-Vis spectra of all complexes were measured and investigated in detail. The emission and absorption spectra of the three complexes and their corresponding ligands are compared and analyzed. (C) 2013 Elsevier B.V. All rights reserved.
