Synthesis, Structural Characterisation, and Cytotoxicity Studies of Bi, W, and Mo containing Homo- and Hetero-bimetallic Polyoxometalates
Senevirathna, D.; Werrett, M.; Kubeil, M.ORC; Stephan, H.ORC; Andrews, P.
Three new and different homo- and hetero-bimetallic polyoxometalate (POM) species have been synthesised by simple one-pot synthetic methods utilising naturally occurring bismite (Bi2O3) (or Bi(NO3)3·5H2O) and aryl sulfonic acids. The POM species isolated are {(NH4)14[Bi2W22O76]·14H2O} (1·14H2O), {NH4[Bi(DMSO)7][Mo8O26]·H2O} (2·H2O) and {[(NH4)4(Mo36O108(OH)4·16H2O)]·45H2O} (3·45H2O). The compounds have been characterised by X-ray crystallography, energy dispersive X-ray spectroscopy (EDX), powdered X-ray diffraction (PXRD), mass spectrometry (ESI-MS), Raman spectroscopy, thermogravimetric (TGA) and ICP analyis. In vitro cytoxicity and proliferation studies conducted on 1 and 3, highlight the low toxicity of these species.
