Abstract

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 van der Waals forces were observed. Two of the THF mol­ecules are disordered over two positions.
