Size and shape trump charge in interactions of oxovanadates with self-assembled interfaces: application of continuous shape measure analysis to the decavanadate anion

Using ⁵¹V NMR spectroscopy, dynamic light scattering and continuous shape analysis to characterize two polyoxometalate-encapsulation in reverse micelles.

Hexakis(dimethyl-ammonium) di-μ(6)-oxido-tetra-μ(3)-oxido-tetra-deca-μ(2)-oxido-octa-oxidodeca-vanadate(V) monohydrate

In the title compound, (C(2)H(8)N)(6)[V(10)O(28)]·H(2)O, the [V(10)O(28)](6-) polymetalate anion has crystallographic mirror symmetry with six V atoms and 12 O atoms lying on the mirror plane. Each of the V(V) atoms adopts a distorted octa-hedral geometry. Eight terminal O atoms are bonded to V(V) atoms with double bonds and the others act as bridging atoms. In the crystal structure, a network of N-H⋯O and O-H⋯O hydrogen bonds helps to establish the packing.
