title: Di-μ-hydroxido-κO:O-μ-trifluoro-methane-sulfonato-κO:O'-bis-[(5,5'-dimethyl-2,2-bipyridine-κN,N')(η-penta-methyl-cyclo-penta-dien-yl)ytterbium(III)] tetra-phenyl-borate 5,5'-dimethyl-2,2-bipyridine.
abstract: The title compound, [Yb(2)(CF(3)O(3)S)(C(10)H(15))(2)(OH)(2)(C(12)H(12)N(2))(2)](C(24)H(20)B)·C(12)H(12)N(2), crystallizes as a half-sandwich complex with a bridging trifluoro-methane-sulfonate 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.
