Abstract

By using mixed rigid and flexible organic ligands, three Keggin based compounds, [Ag6(tbz)4(bmz)2(H3PW12O40)]·4H2O (1), [Ag(H2bdpm)2(H2PMo12O40)]·7.5H2O (2), and [Ag4(tbz)2(H2bdpm)2(HPMo12O40)]·2H2O (3) (Htbz = thiabendazole, Hbmz = benzimidazole, H2bdpm = 1,1'-bis(3,5-dimethyl-1H-pyrazolate)methane), were hydrothermally synthesized and structurally characterized. Through adopting rigid Htbz ligands, compound 1 with hexa-nuclear Ag(I) clusters has been obtained. These hexa-nuclear clusters are linked by Keggin anions alternately to form a one dimensional (1D) chain. In compound , the organic moiety is the flexible H2bdpm ligand. The Keggin anions are fused by [Ag(H2bdpm)2](+) subunits to form a 1D chain. In compound 3, the rigid Htbz and the flexible H2bdpm cooperate to modify the anions. Two tbz and two H2bdpm are fused by four Ag(I) ions to construct a tetra-nuclear Ag(I) cycle. The anions connect these cycles through Ag-O bonds alternately to form a 1D chain. Adjacent chains arrange parallel to build a 2D layer. The chains in the adjacent layers are vertically packed and linked by Ag-O bonds to construct a 3D framework. The electrochemical and photocatalytic properties of the title compounds have been studied. Furthermore, w...Continue Reading

Anthelmintics

Anthelmintics or antihelminthics are a group of antiparasitic drugs that expel parasitic worms (helminths) and other internal parasites from the body by either stunning or killing them and without causing significant damage to the host. Discover the latest research on anthelmintics here.
