A sterically crowded ytterbium(II) thiol­ate: trans-bis(2,4,6,2′',4′′,6′′-hexaiso­propyl-1,1′:3′,1′′-ter­phenyl-2′-thiol­ato-S)tetrakis­(tetra­hydro­furan-O)­ytterbium(II)

In the title complex [Yb(SAr*)₂(thf)₄] (Ar* is 2,6-Trip₂C₆H₃, C₃₆H₄₉S, where Trip is 2,4,6-ⁱPr₃C₆H₂; thf is tetrahydro­furan, C₄H₈O), the Yb atom occupies a special position on the inversion center. It shows a slightly distorted trans-octahedral environment formed by the O atoms of four tetra­hydro­furan ligands (average Yb—O 2.400 Å) and the S atoms of two thiol­ate ligands [Yb—S 2.8023 (13) Å]. The overcrowding caused by the sterically encumbered Ar* ligands is reflected in the large Yb—S—C angle of 151.16 (16)°.
