title: Tris(thio-cyanato-κN)tris-(triphenyl-phosphine oxide-κO)terbium(III).
abstract: The title compound, [Tb(NCS)3(C18H15OP)3], contains a six-coordinate Tb(II) cation surrounded by three O-bound triphenyl-phosphine oxide ligands and three N-bound thio-cyanate ligands, each in a fac arrangement. There are two crystallographically unique Tb(III) atoms in the asymmetric unit. One Tb(III) atom resides on a threefold rotation axis, while the other has no imposed crystallographic symmetry. The thio-cyanate ligands are bound through N atoms, illustrating the hard-hard bonding principles of metal complex chemistry.
