title: Hexakis(2-amino-pyridinium) di-μ(6)-oxido-tetra-μ(3)-oxido-tetra-deca-μ(2)-oxido-octa-oxidodeca-vanadium(V) dihydrate.
abstract: In the title compound, (C(5)H(7)N(2))(6)[V(10)O(28)]·2H(2)O, the [V(10)O(28)](6-) anion is generated by crystallographic inversion symmetry and each of the five vanadium centres adopts a distorted VO(6) octa-hedral geometry. In the crystal structure, a network of N-H⋯O, N-H⋯(O,O) and O-H⋯O hydrogen bonds helps to establish the packing.
