5-pentamethylcyclopentadienyl)ytterbium(III)] tetraphenylborate 5,5'-dimethyl-2,2-bipyridineAbstract: The title compound, [Yb2(CF3O3S)(C10H15)2(OH)2(C12H12N2)2](C24H20B)·C12H12N2, crystallizes as a half-sandwich complex with a bridging trifluoromethanesulfonate as well as two bridging hydroxide groups. The bound bipyridine ligands have N-C-C-N torsion angles of 13.1 (9) and -12.1 (8)°. The structure also contains an uncoordinated 5,5'-dimethyl-2,2'-bipyridine molecule with an N-C-C-N torsion angle of 169.5 (7)°. The triply bridged Yb centers are 3.5990 (4) Å apart. The Yb-N bond lengths are in the range 2.389 (6)-2.424 (5) Å.
