ABSTRACT: The title compound, [Co(C₁₀H₁₅)(C₂H₄)₂], was prepared by Na/Hg reduction of [Co₂(C₁₀H₁₅)₂(?-Cl)₂] in THF under an ethyl-ene atmosphere and crystallized from pentane at 193?K. The Co-C(olefin) bonds have an average length of 2.022?(2)?Å, while the Co-C(penta-dien-yl) bonds average 2.103?(19)?Å. The olefin C=C bonds are 1.410?(1)?Å. The dihedral angle between the planes defined by the cyclo-penta-dienyl ligand and the two olefin ligands is 0.25?(12)°. In the crystal, mol-ecules are linked into chains by C-H?? inter-actions.

Bis(η(5)-penta-methyl-cyclo-penta-dien-yl)aluminium tetra-bromido-aluminate.

Project description:The title compound, [Al(C10H15)2][AlBr4], was formed during the reduction of a mixture of Cp*AlBr2 and AlBr3. The Al(III) atoms of the two crystallographically independent cations each lie on an inversion center, and the [AlBr4](-) anions are on general positions. At 123 K, the structure exhibits disorder in two of the Br atoms of the [AlBr4](-) ion, with a ratio occupancy of 0.733 (6): 0.267 (3). In the crystal, there is possible weak hydrogen bonding between some methyl groups and Br atoms. The interactions link the moieties in a three-dimensional array.

(μ-Di-tert-butyl-silanediolato)bis-[bis-(η5-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.

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

Project description: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 η(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 [(η(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.

(η-Penta-methyl-cyclo-penta-dien-yl)(η-toluene)-ruthenium(II) hexa-fluorido-phosphate.

Project description:In the title complex, [Ru(C(7)H(8))(C(10)H(15))]PF(6), the cation lies on a mirror plane and the anion lies on an inversion center. The distance between the Ru atom and the centroid of the benzene ring is 1.706 (5) Å and the distance between the Ru atom and the cyclo-penta-dienyl ring is 1.811 (5) Å. The crystal structure is stabilized by weak C-H⋯F hydrogen bonds. The H atoms of the methyl groups which lie on the mirror plane are disordered over two sites with equal occupancies.

(2,2'-Bipyrid-yl-κ(2) N,N')bis-(η(5)-penta-methyl-cyclo-penta-dien-yl)barium.

Project description:In the title compound, [Ba(C10H15)2(C10H8N2)], the Ba-N distances are 2.798 (3) and 2.886 (3) Å, and the Cp ring centroid distances to Ba(2+) are 2.7291 (7) and 2.7192 (9) Å. The angle between the N atoms in the bypyridine ligand and the metal ion is 56.80 (8)° and the N-C-C-N torsion angle in the bi-pyridine ligand is 1.7 (4)°. The bi-pyridine ligand is almost planar, the dihedral angle formed by the intersection of the planes defined by the pyridyl rings being 3.04 (19)°, and the angle between the plane defined by the Ba(2+) ion and the two bipyridyl N atoms and the plane defined by the 12 atoms of the bi-pyridine ligand is 10.2 (3)°. The average Ba-N and Ba-centroid distances are 0.16 and 0.14 Å longer, respectively, than the equivalent distances in the isotypic strontium compound [Kazhdan et al. (2008 ▶). Acta Cryst. E64, m1134]. This difference is in accord with the difference between the ionic radii of 0.16 Å suggested by Shannon [Acta Cryst. (1976 ▶), A32, 751-767].

(η-Cyclo-penta-dien-yl)bis-(triphenyl-phosphane)cobalt(I)-toluene-n-hexane (1/0.20/0.25).

Project description:The title compound, [Co(C(5)H(5))(C(18)H(15)P)(2)]·0.2C(7)H(8)·0.25C(6)H(14), was synthesized by the reaction of cobaltocene, Cp(2)Co, with elemental lithium in tetra-hydro-furan in the presence of two equivalents of PPh(3). The mol-ecular structure displays a cobalt(I) center in a distorted trigonal-planar coordination environment, with one Cp and two phosphane ligands. There are two crystallographically independent mol-ecules in the asymmetric unit besides the disordered solvent molecules.

Bis[bis-(penta-methyl-cyclo-penta-dien-yl)cobalt(III)] tetra-chlorido-cobaltate(II) di-chloro-methane disolvate.

Project description:The title compound, [Co(C10H15)2]2[CoCl4]·2CH2Cl2, was isolated as a dichloromethane solvate and was formed in the reaction between lithium penta-methyl-cyclo-penta-dienide and anyhydrous cobalt(II) chloride in tetra-hydro-furan. There are two deca-methyl-cobaltocenium cations, one tetrachloridocobaltate(II) anion and two di-chloro-methane solvent mol-ecules in the formula unit. There is a slight disorder of the di-chloro-methane solvent which was treated with a two-site model [occupancy rates = 0.765?(4) and 0.235?(4)]. The di-chloro-methane mol-ecules display significant C-H?Cl inter-actions with the tetrachloridocobaltate(II) dianion. The cobalt atom of the deca-methyl-cobaltocenium cation sits on a twofold rotation axis, with only one penta-methyl-cyclo-penta-diene ligand being unique and the second generated by symmetry. The cobalt atom of the [CoCl4](-2) ion sits on a special site with -4 symmetry, with one unique chloride ligand and the others generated by the fourfold inversion axis.

Dicarbon-yl(hexa-methyl-ene-1,3,5,7-tetra-mine-κN(1))(η(5)-penta-methyl-cyclo-penta-dien-yl)iron(II) tetra-fluoridoborate.

Project description:In the title compound, [Fe(C(10)H(15))(C(6)H(12)N(4))(CO)(2)]BF(4), the arrangement around the Fe(II) atom corresponds to a three-legged piano stool. The penta-methyl-cyclo-penta-dienyl (Cp*) ligand occupies three coordination sites, while two CO ligands and one N atom of the hexa-methyl-ene-tetra-mine ligand occupy the remaining coordination sites, completing a pseudo-octahedral geometry. Both the complex cation and the BF(4) (-) anion reside on crystallographic mirror planes. The Fe-N bond length is 2.069 (2) and the Fe-Cp*(centroid) distance is 1.7452 (3) Å.

(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.
