Three silver(I) complexes of the asymmetric tridentate ligand 8-((pyridin-3-yl)methylthio)quinoline (TQMP3), namely [Ag2(TQMP3)2(NO3)2] (1), [Ag2(TQMP3)2(CF3CO2)2] (2) and {[Ag2(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 π–π interactions or H-bonds further extending the structures into 2D nets, while in complex 3, Ag⋯Ag interactions between the rings result in a 1D polymer chain. The antibacterial, antifungal and pesticide activities of the three complexes were tested.
Graphical abstractThe reaction of the semi-rigid tridentate ligand TQMP3 with different silver salts afford discrete or connected dimetallic ring subunits. Assembly of these subunits gives rise to a 1D chain and two 2D nets, sustained by intermolecular interactions. A preliminary bioactivity study indicates that these complexes show distinct antibacterial and pesticide activities.Figure optionsDownload full-size imageDownload as PowerPoint slide
