Dibromo(⁵,⁵-propane-2,2-diyldicyclopentadienyl)zirconium(IV)

M. Erben, I. Císarová, J. Vinklárek and M. Picka

Abstract: The title compound, [ZrBr₂(C₁₃H₂₄)], contains a pseudo-tetrahedral Zr^IV centre involving two ⁵-bonded cyclopentadienyl rings [Zr-Cg = 2.1843 (12) Å; Cg is the centroid of a cyclopentadienyl ring] and two Br atoms [Zr-Br = 2.5828 (5) and 2.5879 (6) Å]. The angle Cg1-Zr-Cg2 is constrained to a value of 116.80 (5)° due to the presence of a short interannular 2,2-propylidene bridge. The Zr and Br atoms lie on a crystallographic mirror plane, which bisects the organic ligand.
