Hexakis(dimethyl­ammonium) di-μ6-oxido-tetra-μ3-oxido-tetra­deca-μ2-oxido-octa­oxidodeca­vanadate(V) monohydrate

In the title compound, (C2H8N)6[V10O28]·H2O, the [V10O28]6− polymetalate anion has crystallographic mirror symmetry with six V atoms and 12 O atoms lying on the mirror plane. Each of the VV atoms adopts a distorted octa­hedral geometry. Eight terminal O atoms are bonded to VV 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.
