(Received 8 November 2012; accepted 16 November 2012; online 24 November 2012)

The title compound, [Tb(NCS)3(C18H15OP)3], contains a six-coordinate TbII cation surrounded by three O-bound triphenyl­phosphine oxide ligands and three N-bound thio­cyanate ligands, each in a fac arrangement. There are two crystallographically unique TbIII atoms in the asymmetric unit. One TbIII atom resides on a threefold rotation axis, while the other has no imposed crystallographic symmetry. The thio­cyanate ligands are bound through N atoms, illustrating the hard–hard bonding principles of metal complex chemistry.

Supporting information


Comment top

Lanthanide complexes containing triphenylphosphine oxides have been studied previously (Bowden et al., 2012; Cousins & Hart, 1967, 1968; Feazell et al., 2004) and are particularly interesting due to their tendency to simultaneously present a large number of these bulky ligands. In complexes of the larger lanthanides, such as [Nd(NCS)3{OP(C6H5)3}4], four triphenylphosphine oxide ligands are able to coordinate the metal center (Feazell et al., 2004). With smallar lanthanide ions, such as Tb(III) in the title compound, [Tb(NCS)3{OP(C6H5)3}3], only three phosphine ligands are observed to coordinate. Even with a 1:4 mol ratio of terbium(III) nitrate to triphenylphosphine oxide in the synthetic strategy, there are only three triphenylphosphine oxide ligands that bind to the terbium center in the resultant products. In related lanthanide complexes containing triethylphosphine oxide ligands, the larger, lighter lanthanide ions contain three phosphine ligands and the smaller, heavier lanthanide ions contain only two ligands (Bowden et al., 2012), which is also consistent with the trend observed in structural reports in the triphenylphosphine oxide complexes reported earlier and reported here. Interestingly, it seems apparent that the anhydrous nature of the lanthanide triphenylphosphine oxide systems are dominant as the title compound and past structural reports alike show this behaviour.

Experimental top

An ethanol solution of terbium(III) nitrate hydrate (1 mmol) and potassium thiocyanate (5 mmol) were combined. The precipitated KNO3 was removed by filtration from the reaction mixture and was discarded. After filtration, the resulting mixture was combined with an ethanol solution of triphenylphosphine oxide (4 mmol). The solution volume was reduced and the title compound crystallized as colourless single Tris(thiocyanato-κN)tris(triphenylphosphine oxide-κO)terbium(III)crystals from the solution after approximately one hour. No recrystallization was needed.

Refinement top

H atoms were placed in calculated positions and allowed to ride during subsequent refinement, with C—H = 0.93 Å and Uiso(H) = 1.2Ueq(C).

Special details top

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.
