title: 4,4'-Diazenediyldipyridinium (4-pyridyldiazen-yl)pyridinium octa-cyanidomolyb-date(V) tetra-hydrate.
abstract: The structure of the title complex, (C(10)H(10)N(4))(C(10)H(9)N(4))[Mo(CN)(8)]·4H(2)O, consists of 4,4'-diazenediyldipyridinium and (4-pyridyldiazen-yl)pyridinium cations disordered over the same site, an [Mo(CN)(8)](3-) anion and four uncoordinated water mol-ecules. The cations (crystallographic symmetry, 2) and the [Mo(CN)(8)](3-) anion (crystallographic symmetry, 222) are arranged in an alternating fashion, forming a two-dimensional layered structure through hydrogen bonds. Hydrogen bonds, π-π stacking inter-actions (shortest distance = 4.7872 Å) and van der Waals forces between adjacent layers generate a three-dimensional supra-molecular structure.
