The selenite-capped polyoxo-4-aurate(III), Au III _4O _4(Se IVO _3) _4 ~(4-)

摘要

The discrete heteropolyaurate Au ~(III) _4O _4(Se IVO _3) _4 ~(4-) (Au _4Se _4) represents only the second member of this class ever reported, and was synthesized via one-pot room temperature condensation in aqueous medium. Au _4Se _4 was structurally characterized in the solid state and in solution by single-crystal XRD, TGA, FT-IR, ~(77)Se NMR, mass spectrometry and electrochemistry.
