چکیده
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.

The title co-crystal, [Eu(NCS)3(C18H15OP)3][Eu(NCS)2(NO3)(C18H15OP)3], contains two distinct neutral complexes. Each complex has threefold symmetry about its central Eu(3+) ion. As a result, the nitrate-containing mol-ecule contains disorder of its bidentate nitrate and two N-bound thio-cyanate anions, while the [Eu(NCS)3(OPPh3)3] complex is fully ordered. There is a weak π-π stacking inter-act...

In the crystal structure of title compound, [Sm(NCS)(3)(C(14)H(13)NO(2))(3)], two of the zwitterionic Schiff base 6-meth-oxy-2-(phenyl-iminiometh-yl)phenolate ligands coordinate to the Sm(III) atom in a bidentate fashion via the phenolate and meth-oxy O atoms. The third Schiff base ligand is monodentate, binding only through the phenolate O atom. The coordination sphere of the eight-coordinate ...
