Abstract

Bis(η⁵-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)borane(2-)]zirconium, [Zr(C₅H₅)₂(C₄₇H₆₃BF ₁₀O₁₂Si₇)], 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 [(C₆F ₅)₂B] moiety is bound to the silsesquioxane through an O atom, forming an Si-O-B bond angle of 168.4 (4)°. 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.
