Abstract
The title compound, (C10H10N2)(2)[Mo8O26], was produced by hydrothermal rea ction of an acidified aqueous solution of H2MoO4, 4,4'-bipyridine and NiCl2 . 6H(2)O. The structure of the title compound consists of the beta -octamol ybdate anion having a center of symmetry and protonated 4,4'-bipyridine cat ions. The distances between Mo and O atoms shared by two or more neighborin g {MoO6} octahedra are in the range 1.750 (2)-2.450 (2) Angstrom and those between Mo and terminal O atoms in the range 1.696 (3)-1.720 (3) Angstrom. The N-H . . .O hydrogen-bond lengths are in the range 2.722 (4)-2.755 (4) A ngstrom.
