Di-?-hydroxido-?O:O-?-trifluoro-methane-sulfonato-?O:O'-bis-[(5,5'-dimethyl-2,2-bipyridine-?N,N')(?-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.
