Crystal structure of bis-(?(5)-cyclo-penta-dien-yl)(2,3-di-ethyl-butane-1,4-di-yl)hafnium(IV).

ABSTRACT: The title compound, [Hf(C5H5)2(C8H16)], proves a structural motif of hafna-cyclo-pentane besides the coordination of two cyclo-penta-dienyl ligands in an ?(5)-fashion. The hafna-cyclo-pentane ring has a twist conformation and is substituted by two ethyl groups in the ?,?'-positions, which are trans orientated to each other. One cyclo-penta-dienyl ring and one ethyl group are each disordered over two positions with site-occupancy ratios of 0.679?(15):0.321?(15) and 0.702?(18):0.298?(18), respectively.

The title compound, [Hf(C5H5)2(C8H16)], proves a structural motif of hafna-cyclo-pentane besides the coordination of two cyclo-penta-dienyl ligands in an η(5)-fashion. The hafna-cyclo-pentane ring has a twist conformation and is substituted by two ethyl groups in the β,β'-positions, which are trans orientated to each other. One cyclo-penta-dienyl ring and one ethyl group are each disordered over two positions with site-occupancy ratios of 0.679 (15):0.321 (15) and 0.702 (18):0.298 (18), respecti ...[more]

Crystal structure of di-n-but-yl-bis-(? (5)-penta-methyl-cyclo-penta-dien-yl)hafnium(IV).

Project description:The crystal structure of the title compound, [Hf(C10H15)2(C4H9)2], reveals two independent mol-ecules in the asymmetric unit. The diffraction experiment was performed with a racemically twinned crystal showing a 0.529?(5):0.471?(5) component ratio. Each Hf(IV) atom is coordinated by two penta-methyl-cyclo-penta-dienyl and two n-butyl ligands in a distorted tetra-hedral geometry, with the cyclo-penta-dienyl rings inclined to one another by 45.11?(15) and 45.37?(16)°. In contrast to the isostructural di(n-butyl)bis(? (5)-penta-methyl-cyclo-penta-dien-yl)zirconium(IV) complex with a noticeable difference in the Zr-butyl bonding, the Hf-Cbut-yl bond lengths differ from each other by no more than 0.039?(3)?Å.

Project description:The mol-ecule of the title organometallic hafnium(IV) com-pound, [Hf(CH3)3(C13H21)] or [HfMe3(?(5)-C5H3-1,3- (t) Bu2)], adopts the classical three-legged piano-stool geometry for mono-cyclo-penta-dienylhafnium(IV) derivatives with the three methyl groups bonded to the Hf(IV) atom at the legs.

Project description:Alkyl zirconocene cations have been of considerable inter-est as reactive species in many polymerization processes. In the crystal structure of the title compound, [Zr(C12H19)(C5H5)2](C36HB2F30O), the [Zr(C5H5)2((t-Bu)C=C(H)-C2(t-Bu))](+) cation displays a buta-1-en-3-yne ligand side-on coordinated to a typical bent zirconocene [centroid(cp)-Zr-centroid(cp) = 131.4?(3)°, Zr-C(buta-1-en-3-yne) = 2.255?(3), 2.597?(3) and 2.452?(2)?Å].

Dibromido[bis-(η-cyclo-penta-dien-yl)dimethyl-silane]zirconium(IV).

Project description:The title mol-ecule, [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 tetra-hedral 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 mol-ecule indicate that the inter-action 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.
