title: A fluorophenylboron-functionalized zirconium silsesquioxane complex.
abstract: Bis(eta5-cyclopentadienyl)[rel-(1R,5S,7R,14S)-(1,3,5,7,9,11,14-heptacyclopentyl-7,14-dioxidotricyclo[7.3.3(1,9).1(5,11)]heptasiloxan-3-yloxy)bis(pentafluorophenyl)borane2-]zirconium, [Zr(C5H5)2(C47H63BF10O12Si7)], consists of [ZrCp2] (Cp is cyclopentadienyl) and [(C6F5)2B] moieties bound to a silsesquioxane core. The silsesquioxane binds to the Zr atom through two of its O atoms to form a distorted tetrahedron. The [(C6F5)2B] moiety is bound to the silsesquioxane through an O atom, forming an Si-O-B bond angle of 168.4 (4) degrees. The steric and electronic effects of the Zr atom and the borate moieties force the silsesquioxane core to distort. These distortions can be seen by examination of the Si-O-Si bond angles.
