?-Oxido-bis-{bis-[(penta-fluoro-phen-yl)methano-lato](?-penta-methyl-cyclo-penta-dien-yl)titanium(IV)}.

ABSTRACT: The dinuclear title complex, [Ti(2)(C(10)H(15))(2)(C(7)H(2)F(5)O)(4)O], features two Ti(IV) atoms bridged by an O atom. Each Ti atom is bonded to a ?(5)-penta-methyl-cyclo-penta-dienyl ring, two (penta-fluoro-phen-yl)methano-late anions and to the bridging O atom. The environment around each Ti atom can be considered as a distorted tetra-hedron.

Project description:The dinuclear title complex, [Ti(2)(C(10)H(15))(2)(C(6)F(5)O)(4)O], features two Ti(IV) atoms bridged by an O atom, which lies on an inversion centre. The Ti(IV) atom is bonded to a ?(5)-penta-methyl-cyclo-penta-dienyl ring, two penta-fluoro-phenolate anions and to the bridging O atom. The environment around the Ti(IV) atom can be considered as a distorted tetra-hedron. The cyclo-penta-dienyl ring is disordered over two sets of sites [site occupancy = 0.824?(8) for the major component].

Iodidobis(?-penta-methyl-cyclo-penta-dien-yl)titanium(III).

Project description:In the title complex mol-ecule, [Ti(C(10)H(15))(2)I], the paramagnetic Ti(III) atom is coordinated by two penta-methyl-cyclo-penta-dienyl (Cp*) ligands and one iodide ligand. The two Cp* ligands are in a staggered orientation. The coordination geometry at the titanium atom can be described as distorted trigonal-planar.

Penta-carbonyl-2κC-chlorido-1κCl-bis-[1(η)-cyclo-penta-dien-yl](μ-α-oxido-benzyl-idene-1:2κO:C)titanium(IV)tungsten(0).

Project description:The title compound, [TiW(C(5)H(5))(2)(C(7)H(5)O)Cl(CO)(5)], consists of two metal centres, with a (tungstenpenta-carbon-yl)oxy-phenyl-carbene unit coordinated by a titanocene chloride. The oxycarbene group is nearly planar, with the phenyl ring twisted by an angle of 39.1 (2)° with respect to this plane. One of the cyclo-penta-dienyl rings undergoes an offset face-to-face π-π inter-action [3.544 (6) Å] with the symmetry-related cyclo-penta-dienyl ring of a neighbouring mol-ecule.

{N,N-Bis[bis-(2,2,2-tri-fluoro-eth-oxy)phosphan-yl]methyl-amine-κ(2) P,P'}bis-(η(5)-cyclo-penta-dien-yl)titanium(II).

Project description:The title compound, [Ti(C5H5)2(C9H11F12NO4P2)], is a four-membered titanacycle obtained from the reaction of Cp2Ti(η(2)-Me3SiC2SiMe3) and CH3N[P(OCH2CF3)2]2 {N,N-bis-[bis-(tri-fluoro-eth-oxy)phosphan-yl]methyl-amine, tfepma}. The Ti(II) atom is coordinated by two cyclo-penta-dienyl (Cp) ligands and the chelating tfepma ligand in a strongly distorted tetra-hedral geometry. The mol-ecule is located on a mirror plane.

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.

(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.

[1-Dimethyl-silyl-2-phenyl-3-(?-tetra-methyl-cyclo-penta-dien-yl)-prop-1-en-1-yl-?C](?-penta-methyl-cyclo-penta-dien-yl)titanium(III).

Project description:The title compound, [Ti(C(10)H(15))(C(20)H(26)Si)], was obtained from the reaction of [Ti{?(5):?(1)-C(5)Me(4)(CH(2))}(?(5)-C(5)Me(5))] with the alkynylsilane PhC(2)SiMe(2)H. The complex crystallizes with two independent mol-ecules in the asymmetric unit, which differ in the conformation of the propenyl unit, resulting in their having opposite helicity. No inter-molecular inter-actions or inter-actions involving the Si-H bond are present. The observed geometrical parameters are unexceptional compared to known structures of the same type.

Project description:The title dinuclear half-sandwich complex, [CpTi(OCH=CH2)(?2-N-iPr)]2 (Cp = cyclo-penta-dien-yl; iPr = isopropyl), was ob-tained from the reaction of Cp2TiCl2, n-butyl-lithium and iso-propyl-amine in tetra-hydro-furan. Each Ti(IV) atom is coordinated by one Cp ligand, one vin-yloxy unit and two bridging imido groups in a strongly distorted tetra-hedral geometry. There are two half mol-ecules in the asymmetric unit, such that whole mol-ecules being generated by inversion symmetry.
