Bis(?-cyclo-penta-dien-yl)bis-(2,4,6-tri-methyl-phenyl-tellurolato)zirconium(IV).

ABSTRACT: The structure of the title compound, [Zr(C(5)H(5))(2)(C(9)H(11)Te)(2)], consists of a zirconium(IV) centre bonded to two ?(5)-coord-inated cyclo-penta-dienyl groups and two mesityltellurolate ligands; the discrete mol-ecule has crystallographic twofold rotation symmetry. The structural parameters compared with those in [(?(5)-Me(5)Cp)(2)Zr(TePh)(2)] [Howard, Trnka & Parkin (1995 ?). Inorg. Chem.34, 5900-5909] show that the greater steric demands of the bulky mesityl substituents are accommodated by widening Te-Zr-Te (?8°) and by more acute Zr-Te-C (?5°) angles, although the Zr-Te distances are essentially the same. The crystal studied exhibited some inversion twinning.

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.

(tert-Butyl-imido)bis-(η-cyclo-penta-dien-yl)pyridine-zirconium(IV).

Project description:The title compound, [Zr(C(5)H(5))(2)(C(4)H(9)N)(C(5)H(5)N)], was obtained from the reaction of (C(5)H(5))(2)Zr(py)(η(2)-Me(3)SiC(2)SiMe(3)) (py is pyridine) and (t)BuN=C=N(t)Bu alongside the formation of (C(5)H(5))(2)Zr(CN(t)Bu)(η(2)-Me(3)SiC(2)SiMe(3)). The zirconium atom is coordinated in a distorted tetra-hedral geometry by two cyclo-penta-dienyl ligands, a pyridine ligand, and a tert-butyl-imido ligand via a Zr=N double bond. The tert-butyl group is disordered over two positions in a 0.634 (5):0.366 (5) ratio.

(Cyanido-κC)(2,2-di-phenyl-acetamido-κ(2) N,O)bis-(η(5)-penta-methyl-cyclo-penta-dien-yl)zirconium(IV).

Project description:In the title compound, [Zr(C10H15)2(C14H12NO)(CN)], the Zr(IV) atom is coordinated by two penta-methyl-cyclo-penta-dienyl ligands, the amidate ligand via the N and O atoms, and an additional C N ligand. The four-membered metallacycle is nearly planar (r.m.s. deviation = 0.008 Å). In the crystal, the mol-ecules are connected into centrosymmetric dimers via pairs of N-H⋯N hydrogen bonds.

cyclo-Tri-?-oxido-tris-{[(?,?)-1,2-bis-(cyclo-penta-dien-yl)-1,1,2,2-tetra-methyl-disilane]zirconium(IV)}: a trimeric disila-bridged oxidozirconocene.

Project description:The title compound, [Zr(3)(C(14)H(20)Si(2))(3)O(3)], consists of three disila-bridged zirconocene units, which are connected via an oxide ligand, forming a nearly planar six-membered ring with a maximum displacement of 0.0191?(8)?Å.

Bis(η-penta-methyl-cyclo-penta-dien-yl)cobalt(II).

Project description:The crystal structure of the title compound, deca-methyl-cobaltocene, [Co(C(10)H(15))(2)], has been determined. High-quality single crystals were grown from a cold saturated hexa-methyl-disiloxane solution. The structure is related to the manganese and iron analogs. The molecule has D(5d) symmetry, with the Co atom in a crystallographic 2/m position. The cobalt-centroid(C(5)) distance is 1.71Å and the centroid(C(5))-Co-centroid(C(5)) angle is 180°, by symmetry.

Penta-carbonyl-2κC-chlorido-1κCl-bis-[1(η)-cyclo-penta-dien-yl][μ-oxido(phenyl)methylene-1:2κO:C]hafnium(IV)tungsten(0).

Project description:The title compound, [HfW(C(5)H(5))(2)(C(7)H(5)O)Cl(CO)(5)] or [W(CO)(5)(C(7)H(5)O){Hf(C(5)H(5))(2)Cl}], contains two metal centres, with a (tungstenpenta-carbon-yl)oxy-phenyl-carbene unit coordinated to a hafnocene chloride. The Hf-O-C angle is nearly linear, and the C=O distance is slightly shorter than for equivalent alkoxy-carbenes. One of the cyclo-penta-dienyl (Cp) rings undergoes an offset face-to-face π-π inter-action [3.495 (7) Å] with the symmetry-related Cp ring of a neighbouring mol-ecule.

(μ-Di-<i>tert</i>-butyl-silanediolato)bis-[bis-(η<sup>5</sup>-cyclo-penta-dien-yl)methyl-zirconium].

Project description:The reaction of t-Bu2Si(OH)2 with two equivalents of Cp2Zr(CH3)2 produces the title t-Bu2SiO2-siloxide bridged dimer, [Zr2(CH3)2(C5H5)4(C8H18O2Si)] or [Cp2Zr(CH3)]2[μ-t-Bu2SiO2] (1), where one methyl group is retained per zirconium atom. The same product is obtained at room temperature even when equimolar ratios of the silanediol and Cp2Zr(CH3)2 are used. Attempts to thermally eliminate methane and produce a bridging methyl-ene complex resulted in decomposition. The crystal structure of 1 displays typical Zr-CH3 and Zr-O distances but the Si-O distance [1.628 (2) Å] and O-Si-O angle [110.86 (15)°] are among the largest observed in this family of compounds suggesting steric crowding between the t-Bu substituents of the silicon atom and the cyclo-penta-dienyl groups. The silicon atom lies on a crystallographic twofold axis and both Cp rings are disordered over two orientations of equal occupancy.

(Glycol-κO,O')nitros-yl(η-penta-methyl-cyclo-penta-dien-yl)ruthenium(II) bis-(tri-fluoro-methane-sulfonate).

Project description:The title compound, [Ru(C(10)H(15))(NO)(HOCH(2)CH(2)OH)](CF(3)SO(3))(2), possesses a three-legged piano-stool geometry around the Ru atom, with an average Ru-O distance of 2.120 (6) Å and an Ru-N-O angle of 159.45 (14)°. The ethyl-eneglycol ligand forms a non-planar metallacyclic ring by chelating the Ru atom via the O atoms. The O⋯O distances of 2.554 (2) and 2.568 (2) Å are indicative of hydrogen bonding between coordinated ethyl-eneglycol and outer-sphere trifluoro-methane-sulfonate fragments. The crystal packing is stabilized by ionic forces and several CH(3)⋯·F (2.585 and 2.640 Å) and CH(3)⋯O inter-actions (2.391, 2.678, 2.694 and 2.699 Å) between the penta-methyl-cyclo-penta-dienyl ligand and trifluoro-methane-sulfonate anion. There is noticeable short inter-molecular contact [2.9039 (16) Å], between an O atom of the SO(3) group and a C atom of the penta-methyl-cyclo-penta-dienyl ligand.

(η-Penta-methyl-cyclo-penta-dien-yl)(η-p-toluene-sulfonamide)ruthenium(II) tetra-phenyl-borate.

Project description:The crystal structure of the title compound, [Ru(C(10)H(15))(C(7)H(9)NO(2)S)]C(24)H(20)B, has been determined as part of our investigation into the structural and biological properties of organometallic Ru(II)-arene-Cp* complex salts of the type [R-PhRuCp*](+)·X(-) (where Cp* is penta-methyl-cyclo-penta-diene). Tethering the RuCp* group to the benzene ring of p-toluene-sulfonamide results in only minor changes to the mol-ecular geometry of the sulfonamide, but, together with crystallization as the [BPh(4)](-) salt, effectively blocks involvement of the sulfonamide group in N-H⋯O hydrogen-bonding networks.

Crystal structure of (1,3-di-tert-butyl-η(5)-cyclo-penta-dien-yl)tri-methyl-hafnium(IV).

Project description:The mol-ecule of the title organometallic hafnium(IV) com-pound, [Hf(CH3)3(C13H21)] or [HfMe3(η(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. The C atoms of the two tert-butyl group bonded to the cyclo-penta-dienyl (Cp) ring are 0.132 (5) and 0.154 (6) Å above the Cp least-squares plane. There are no significant inter-molecular inter-actions present between the mol-ecules in the crystal structure.
