In the title compound, [Tb(C10H8N2O2)4(H2O)4][W(CN)8], both metal atoms are eight-coordinated. The TbIII ion displays a dodecahedral geometry, while the Wv ion exhibits a distorted square-antiprismatic geometry. The Tb atoms are located on a special position of -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].

Single crystals of the title compound were prepared at room temperature in the dark by slow diffusion of a H2O solution (3 ml) containing Tb(NO3)3.6H2O (0.05 mmol) and 4,4'-dpdo (0.05 mmol) into a CH3CN solution (15 ml) of [HN(n-C4H9)3]3[W(CN)8].4H2O (0.05 mmol) (Bok et al., 1975). After two weeks, yellow block crystals were obtained.
All non-hydrogen atoms were refined with anisotropic thermal parameters. The H atoms of 4,4'-bpdo ligands were calculated at idealized positions with C—H = 0.93 Å and included in the
in a riding mode with U(H) set to 1.2 Ueq(C). The H atoms bound to oxygen atom from coordinated water molecule were located from difference maps and refined as riding with O—H = 0.85 Å and U(H) set to 1.2Ueq(O).Data collection: SMART (Bruker, 2004); cell

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

In the past few years, a considerable effort on crystal engineering has been devoted to the design and construction of octacyanometallates [M(CN)8]3-/4- (M = Mo, W)-based magnets (Sieklucka et al., 2011). The combination of [M(CN)8]3- as a carrier of unpaired spin with transition- or lanthanide-metal cations has produced various dimensional molecular structures, and further displayed intriguing magnetic properties (Zhou et al., 2010). Recently, we have used [W(CN)8]3- as the building block to react with Tb3+ and 4,4'-bipyridine dioxide (4,4'-dpdo), obtaining a new ionic compound, [Tb(4,4'-dpdo)4(H2O)4][W(CN)8], which is isomorphous to [Tb(4,4'-dpdo)4(H2O)4][Mo(CN)8] reported previously by our group (Qian & Yuan, 2011).
In the structure, each Tb atom is located on a special position of site symmetry 4, whereas each Mo atom is located on a twofold rotation axis. The Wv exhibits a distorted square antiprism, while the TbIII center displays an eight-coordinated decahedron geometry with 2.386 Å of the mean Tb—O bond length. The average W—C and C—N distances are 2.174 and 1.158 Å, respectively, while the W—CN bond angles are nearly linear with a maximum deviation from linearity of 4.0°. The neighboring cations are linked through O—H···O hydrogen bonds, Table 1.
