Molybdenum–Vanadium Oxide Clusters: Syntheses, Structures and Antibacterial Properties

Abstract

The design and synthesis of polyoxometalates (POMs), a type of inorganic compounds, are of great interest due to their interesting structural properties as well as their extensive theoretical and practical applications in catalysis, electrical conductivity, magnetism, optics and medicine. Therefore, in this study two molybdovanadates [Cu(phen)2]3[Mo6V2O26]·4H2O and [Cu(bpy)2]3[Mo6V2O26]·4H2O have been prepared by the reaction of the [Mo6V2O26]6- anion with Cu(CH3COO)2 and 1,10-phenanthroline/2,2'-bipyridine in aqueous medium; characterized by Fourier Transform Infrared Spectroscopy (FT-IR), Nuclear Magnetic Resonance (1H NMR), Inductively coupled plasma mass spectrometry (ICP-MS), Thermogravimetric Analysis (TGA) and elemental analysis. The compounds show antibacterial activity against Escherichia coli (E. Coli) and Staphylococcus aureus (S. Aureus).
