title: Tris(2,2'-bipyridine)-nickel(II) hexa-molybdate.
abstract: The asymmetric unit of the title compound, [Ni(C(10)H(8)N(2))(3)][Mo(6)O(19)], consists of one complex [(Ni(C(10)H(8)N(2))(3)](2+) cation and one Lindqvist-type [Mo(6)O(19)](2-) polyanion. The Ni(2+) ion is in a distorted octa-hedral coordination by six N atoms from three chelating 2,2'-bipyridine ligands. The Lindqvist-type anion exhibits the characteristic Mo-O bond-length distribution, with the shortest bonds being the Mo-O(terminal) bonds [mean = 1.679 (2) Å] and the longest being those to the central O atom [mean = 2.318 (7) Å]. A number of C-H⋯O inter-actions contribute to the crystal packing.
