Abstract

The unique polyoxometalate compound Na20[{MoVIO3- (H2O)}10{VIVO(H2O)}20{(MoVI/MoVI5O21)(H2O)3}10({MoVI- O2(H2O)2}5/2)2 ({NaSO4}5)2]·xH2O 1 (x ≈ 170) shows remarkable structural features: e.g. (i) {MoVI/MoVI5}-type pentagons as building blocks (being present in the relevant reaction medium as disposition), (ii) a ‘magnetic ring-shaped band’ built up by ten linked {VIV3} triangles having common corners and (iii) two {NaSO4}5 rings encapsulated inside the cavity of an icosidodecahedron formed by twenty triangular and twelve pentagonal faces built up by ten MoVI and twenty VIV centres, respectively.
