Özet

A series of six V-substituted Lindqvist type polyoxometalate [M2V4O19]4− (M = Mo, W) have been successfully prepared in good yields. Their structures were identified using elemental analysis, FT-IR, 1H NMR, 31P NMR, ICP-MS, and TGA. The antibacterial activity of these new series of V-substituted Lindqvist type polyoxometalates were carried out by disc diffusion method with gram-positive Staphylcoccus aureus ATCC 25923 and gram-negative Escherichia coli ATCC 25922 bacteria and some of the tested polyoxometalates have shown greater antibacterial activity than Ofloxacin (standard antibiotic). Moreover the MIC values of [Ph4P]4[W2V4O19] (1b) and [Ph4P]4[Mo2V4O19] (2b), against Staphylcoccus aureus bacterial strain are 1.22 and 9.76 μg/ml respectively.
