Poly[tetrakis(4-aminopyridinium) [hexadeca-μ-oxo-decaoxooctamolybdate(VI)]]

J. R. Nelson, A. Narducci Sarjeant and A. J. Norquist

The title compound, {(C₅H₇N₂)₄[Mo₈O₂₆]}_n, contains extended [Mo₈O₂₆]_n⁴ⁿ⁻ chains, built up from distorted MoO₆ octahedra sharing vertices and edges. A network of N—H

O hydrogen bonds helps to stabilize the crystal packing.
