title: Tetra-aqua-tetra-kis-(4,4'-bipyridine dioxide-κO)terbium(III) octa-cyanido-molybdate(V).
abstract: In the title compound, [Tb(C(10)H(8)N(2)O(2))(4)(H(2)O)(4)][Mo(CN)(8)], both metal atoms are eight-coordinated. The Tb(III) atom displays a dodecahedral geometry, while the Mo(V) ion exhibits a distorted square-anti-prismatic geometry. The Tb atoms are located on a special position of site symmetry [Formula: see text], whereas the Mo atoms are located on a twofold rotation axis. The cations are linked by O-H⋯O hydrogen bonds.
