S.-Y. Qian and A.-H. Yuan

Abstract: In the title compound, [Tb(C₁₀H₈N₂O₂)₄(H₂O)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-antiprismatic geometry. The Tb atoms are located on a special position of site symmetry $\\overline{4}$ , whereas the Mo atoms are located on a twofold rotation axis. The cations are linked by O-HO hydrogen bonds.
