The title compound, di-μ-chlorido-dichlorido-1κ2Cl-tetrakis(tetrahydrofuran)-1κ2O,2κ2O-lithiumytterbium(III), [LiYbCl4(C4H8O)4], was prepared by the reaction of YbCl3(THF)3 with LiCl in THF (THF is tetrahydrofuran). The central motif of the structure is a Yb(μ-Cl)2Li ring. The Yb atom is hexacoordinated to four Cl atoms and two THF molecules oriented in a trans fashion. The Li atom has a tetrahedral environment and is coordinated to two Cl atoms and two THF molecules. No intermolecular interactions other than were observed. Two of the THF molecules are disordered over two positions.

YbCl3(THF)3 (200 mg, 0.4 mmol) and LiCl (25.7 mg, 0.6 mmol) were mixed as solids in a schlenk flask and THF (10 ml) was added at ambient temperature. The mixture was stirred for 4 h. During this time, both components dissolved completely. The resulting solution was filtered and the solvent evaporated under vacuum to dryness. The product was obtained in a form of transparent colourless crystals in 86% yield. Single crystals were obtained from a saturated THF solution at -30 °C.
The hydrogen atoms were placed at calculated positions (H—CMethylene = 0.99 Å) and were refined with Uij set to 1.2 of the parent carbon atom. The SIMU, DELU and SAME restraints in SHELXL97 were used in the
of the two disordered THF molecules (O1—C4 and O1a—C4a: occupancies 63 (2):37 (2), O3—C12 and O3a—C12a: occupancies 65 (2):35). The maximum/minimum of the difference electron density is found 1.10 and 1.31Å, respectively, from Li1.Data collection: APEX2 (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. |

Lanthanide compounds containing small ligands can easily form adducts or complex structures with electron donating ligands such as oxygen, halogenides etc. It is well known, that in presence of a Lewis acid such as lithium, mixed metal complexes can be formed. Thus, the reaction of YbCl3(THF)3 with LiCl in THF resulted in the formation of LiYbCl4(THF)4 as the only product (Scheme 1). Two types of chlorine atoms can be observed in the molecule: two terminal ones, which are coordinated to the ytterbium atom, whereas the other two are bridging the ytterbium and lithium atoms. The coordination spheres of the metals are completed by four THF molecules (two per metal) resulting in a hexacoordinated octahedral environment on the ytterbium atom and tetrahedral coordination on the lithium atom. The THF molecules on the ytterbium center are oriented trans to each other with an angle of 179.0 (5)° (for the major position of O1). The values for the cis Cl—Yb—Cl angles show high variation (82.95 (3) – 99.06 (3)°) due to the coordination of Cl1 and Cl2 to the lithium center, which results also in 172.39 (3)° and 171.11 (3)° trans Cl—Yb—Cl angles. The tetrahedron arround the lithium atom is also disordered with the angles ranging from 94.9 (2) to 114.2 (3)°. The molecular structure of LiYbCl4(THF)4 is depicted in Figure 1.
