Descripción
Sumario:The title mol­ecule, [ZrBr(2)(C(12)H(14)Si)], possesses a crystallographically imposed twofold rotational symmetry with the rotation axis passing through the Zr and Si atoms. The Zr(IV) centre is in a distorted tetra­hedral environment defined by two Cp rings of chelating organic ligands and two Br anions. Two five-membered rings form a dihedral angle of 59.7 (2)°. Unequal Zr—C bonds [2.471 (3)–2.556 (3) Å] in the mol­ecule indicate that the inter­action of the central metal with the [(C(5)H(4))(2)SiMe(2)](2−) ligand contains noticeable η(3)-allyl and η(2)-olefin contributions.
