title: Poly[4,4'-imino-dipyridinium [tetra-μ(3)-oxido-tetra-oxido-di-μ(4)-phosphato-κO:O':O'':O'''-tetra-vanadium(V)]].
abstract: In the title salt, {(C(10)H(11)N(3))[V(4)O(8)(PO(4))(2)]}(n), cubane-like [V(4)O(8)](4+) clusters are connected by phosphate anions into anionic [V(4)P(2)O(16)](n) (2n-) layers. These aggregate into the three-dimensional structure via N-H⋯O hydrogen-bonding mechanisms imparted by 4,4'-imino-dipyridinium dications situated between the layers.
