Crystal structure of tris-(phenyl-seleno-lato-κSe)tris-(tetra-hydro-furan-κO)thulium(III)

In the title compound, [Tm(C6H5Se)3(C4H8O)3], the Tm(III) atom lies on a threefold rotation axis and is coordinated by three phenyl-seleno-late ligands and three tetra-hydro-furan ligands leading to a distorted fac-octa-hedral coordination environment. The Tm-Se and Tm-O bond lengths are 2.7692 (17)...

Description
Summary:In the title compound, [Tm(C6H5Se)3(C4H8O)3], the Tm(III) atom lies on a threefold rotation axis and is coordinated by three phenyl-seleno-late ligands and three tetra-hydro-furan ligands leading to a distorted fac-octa-hedral coordination environment. The Tm-Se and Tm-O bond lengths are 2.7692 (17) and 2.345 (10) Å, respectively, and the bond angles are 91.32 (6)° for Se-Tm-Se, 92.6 (2) and 94.4 (2)° for Se-Tm-O, and 81.2 (3)° for O-Tm-O. In the crystal, the discrete complexes are linked by van der Waals inter-actions only. The crystal was refined as a non-merohedral twin (ratio = 0.65:0.35).
