Abstract
In the title compound, [Tb(C(10)H(8)N(2)O(2))(4)(H(2)O)(4)][W(CN)(8)], both metal atoms are eight-coordinated. The Tb(III) ion displays a dodeca-hedral geometry, while the W(v) ion exhibits a distorted square-anti-prismatic geometry. The Tb atoms are located on a special position of site symmetry -4, whereas the W atoms are located on a twofold rotation axis. The cations are linked by O-H⋯O hydrogen bonds. The title compound is isotypic with the corresponding and previously described Mo compound [Qian & Yuan (2011 ▶). Acta Cryst. E67, m845].
