abstract = {The reaction of acidified aqueous solutions of Na2WO4,
NaVO3 and SeO2 in a 16 : 4 : 3 molar ratio gives a
complex mixture of polyoxometalates (POMs) with both WVI and
VV addenda, formulated as
[(SeIVWVIxVV9−xO33)2(WVIO(H2O))(VO)m]n− with x = 4, 5,
6; m = 2 or 3. In solution, the sandwich-type complexes
[(SeIVWVIxVV9−xO33)2(WVIO(H2O))(VO)m]n− slowly lose Se
and convert into [WVI4VV2O19]4− and further to
[WVI5VVO19]3− with a Lindqvist-type structure. These
transformations were monitored with 51V and 77Se NMR,
electrospray mass-spectrometry and capillary
electrophoresis. Crystals of (NMe4)2Na2[(W4V2)O19]·8H2O (1)
and
(NMe4)4.83[(SeW4.57V4.43O33)2(W(O)(H2O))(VO)2.6]·10.57H2O
(2) were isolated and structurally characterized.},
