Abstract
The tri-rhenium(VI) capped Wells-Dawson polyoxometalate, [Re3P2W15O62]6- with quaternary ammonium cations was synthesized by reacting the trivacant lacunary species, [P2W15O56]12- with [ReOCl3(PPh3)2] in an organic solvent. Elemental analysis by thermogravimetry and inductively coupled plasma mass spectroctrometry confirmed the substitution of three rhenium atoms, single-crystal X-ray diffraction as well as infra red spectroscopy showed the complete Wells-Dawson structure. The presence of all three rhenium atoms in one cap is indicated by 31P nuclear magnetic resonance spectroscopy and the electron spin resonance spectrum shows that the tri-rhenium(V) species with three unpaired electrons is low spin, S = 1/2.
