Three silver(I) complexes of the asymmetric tridentate ligand 8-((pyridin-3-yl)methylthio)quinoline (TQMP3), namely [Ag-2(TQMP3)(2)(NO3)(2)] (1), [Ag-2(TQMP3)(2)(CF3CO2)(2)] (2) and [Ag-2(TQMP3)(2)](CF3SO3)(2) (H2O)}(n) (3), have been prepared by the method of layering and diffusing of diethyl ether. The structures of the complexes have been identified by elemental analysis (EA), infrared spectra (IR) and single-crystal diffraction, and are composed of discrete binuclear rings in complexes 1 and 2, with pi-pi interactions or H-bonds further extending the structures into 2D nets, while in complex 3, Ag center dot center dot center dot Ag interactions between the rings result in a 1D polymer chain. The antibacterial, antifungal and pesticide activities of the three complexes were tested. (C) 2008 Elsevier Ltd. All rights reserved.
