{2-[(?-Cyclo-penta-dien-yl)diphenyl-meth-yl]-1H-imidazolido-?N}bis-(N,N-diethyl-amido)-titanium(IV).

ABSTRACT: The chemically achiral title mol-ecule, [Ti(C(4)H(10)N)(2)(C(21)H(16)N(2))], crystallizes in the chiral space group P2(1). All three N atoms coordinating to the Ti(IV) atom adopt planar environments [sums of valence angles = 359.5?(6), 360.0?(7) and 360.0?(6)°], which is indicative of p?-d? donation from all of these N atoms to the metal and, thus, of the formal 18?e(-) nature of the complex. The overall coordination about the Ti(IV) atom is distorted tetra-hedral, assuming the cyclo-penta-dienyl ring occupies one coordination site. The Ti-N(imidazole) amide-type bond is longer by approximately 0.16?Å than the other two Ti-N(amide) bonds.

The chemically achiral title mol-ecule, [Ti(C(4)H(10)N)(2)(C(21)H(16)N(2))], crystallizes in the chiral space group P2(1). All three N atoms coordinating to the Ti(IV) atom adopt planar environments [sums of valence angles = 359.5 (6), 360.0 (7) and 360.0 (6)°], which is indicative of pπ-dπ donation from all of these N atoms to the metal and, thus, of the formal 18 e(-) nature of the complex. The overall coordination about the Ti(IV) atom is distorted tetra-hedral, assuming the cyclo-penta-dieny ...[more]

Project description: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: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.

2-[(Cyclo-penta-1,3-dien-2-yl)diphenyl-meth-yl]-1-methyl-1H-imidazole.

Project description:The title compound, C(22)H(20)N(2), (Ib), forms along with 2-[(cyclo-penta-1,3-dien-1-yl)diphenyl-meth-yl]-1-methyl-1H-imid-azole, (Ia), which differs with respect to the position of the double-bonds in the C(5)H(5) ring, in an approximately 3:7 ratio (Ia:Ib; NMR spectroscopy data). However, in a single crystal, only compound (Ib) is present. H atoms of the CH(2) group (C(5)H(5) ring) were found from the difference Fourier synthesis and refined isotropically using the riding model. Hypothesis on possible presence of the (Ia) isomer in crystal lattice (model with a C(5)H(5) ring disordered between two positions) was especially checked and rejected due to its inconsistency. In the crystal structure, no significant hydrogen-bonding inter-actions between the CH(2) groups of the C(5)H(5) rings and nonsubstituted N-atoms of the imidazole rings were observed. Despite the fact that the chemically achiral compound (I) crystallizes in a chiral space group P2(1)2(1)2(1), neither the absolute structure determination nor assignment of the inversion twinning was possible in the absence of a heavy atom.

Project description:The mol-ecular structure of the title titanium(IV) half-sandwich complex, [Ti(?5-C10H15)(?4-C21H19N)(C12H10N)], shows a three-legged piano-stool geometry at the central TiIV atom, comprising of one penta-methyl-cyclo-penta-dienyl ligand, one bidentate ketimine ligand in an ?4-coordination mode and one monodentate di-phenyl-amide ligand. Except for van der Waals forces, there are no significant inter-molecular inter-actions in the crystal.

[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.

(?-Cyclo-penta-dien-yl)[?-diethyl eth-yl(phen-yl)malonate]iron(II) hexa-fluorido-phosphate.

Project description:At 223?(2)?K, the complexed rings in the iron(II) complex cation of the title salt, [Fe(C(5)H(5))(C(15)H(20)O(4))]PF(6), are almost parallel [dihedral angle between planes = 4.10?(14)°]. Among the C atoms of the complexed arene ring, the quaternary C atom is located at the longest distance from the Fe atom. The F atoms of the PF(6) (-) anion were found to be equally disordered over two sites.

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.
