Bis(diethyl-amido-?N)(diethyl-amine-?N)bis-(2,6-diisopropyl-phenyl-amido-?N)zirconium(IV).

ABSTRACT: In the title compound, [Zr(C(12)H(18)N)(2)(C(4)H(10)N)(2)(C(4)H(11)N)] or [Zr(HNC(6)H(3) (i)Pr(2))(2)(NEt(2))(2)(HNEt(2))], which was obtained by the reaction of Zr(NEt)(4) with (i)Pr(2)C(6)H(3)NH(2), the Zr(IV) atom is in a trigonal-bipiramidal geometry in which the N atoms from two (i)Pr(2)C(6)H(3)NH and one NEt(2) ligand occupy the equatorial positions, and the N atoms of an NEt(2) and an Et(2)NH ligand occupy the apical positions. An intra-molecular N-H?N contact occurs. There are two independent molecules in the asymmetric unit.

Crystal structure of tris-(di-methyl-amido-?N)-bis-(di-methyl-amine-?N)-zirconium(IV) iodide.

Project description:Zirconium amides have become increasingly popular and useful due to their widespread use as precursors to other zirconium complexes and their use in the production of solid oxide fuel cells (SOFCs). Herein we report the mol-ecular structure of tris-(di-methyl-amido)-bis-(di-methyl-amine)-zirconium(IV) iodide, [Zr(C2H6N)3(C2H7N)2]I. The bond lengths and bond angles are consistent with a slightly distorted trigonal-bipyramidal coordination geometry around the metal atom. N?I contacts of 3.6153?(15) and 3.5922?(14)?Å are consistent with the presence of N-H?I inter-actions. These N-H?I inter-actions link the complex cations and iodide anions into extended chains that propagate parallel to the a axis.

2,6-Bis[1-(2,6-diethyl-phenyl-imino)eth-yl]pyridine.

Project description:The title compound, C(29)H(35)N(3), is the product of the condensation reaction between 2,6-diacetyl-pyridine and 2,6-diethyl-aniline. In the mol-ecule, the pyridyl ring is coplanar with the imino functional groups [torsion angles in the range 177.1 (2)-179.9 (2)°. The two 2,6-diethyl-substituted benzene rings are approximately perpendicular to the ethyl-idenepyridine central core, the dihedral angles being 88.7 (1) and 88.4 (1)°, respectively.

1,3-Bis(2,6-diisopropyl-anilino)-1-phenyl-butyl-ium hexa-fluorido-phosphate.

Project description:The cation of the title salt, C(34)H(45)N(2) (+)·PF(6) (-), is a protonated form of an unsymmetrical overcrowded β-imino-amine. The observed bond lengths [C-N = 1.326 (4)-1.341 (4) Å and C-C = 1.383 (4)-1.391 (4) Å] suggest significant delocalization within the π system of the N C C C N backbone.

1,3-Bis(2,6-diisopropyl-phen-yl)imidazolidinium tetra-phenyl-borate dichloro-methane disolvate.

Project description:The title compound, C(27)H(39)N(2) (+)·C(24)H(20)B(-)·2CH(2)Cl(2), is the first reported imidazolidinium cation with the sterically demanding 2,6-diisopropyl-phenyl groups in the 1,3-positions. The crystal structure is stabilized by weak inter-molecular C-H??(arene) inter-actions. Due to the bulky nature of both the flanking 2,6-diisopropyl-phenyl substituents and the tetra-phenyl-borate counter-ion, anion inter-actions with the imidazolidinium H atom in the 2-position are not observed, also a first for this class of ortho-alkyl-substituted Arduengo-type carbene precursors.

Tetra-kis(di-cyclo-hexyl-amido)-zirconium(IV).

Project description:The reaction of ZrCl4 with three equivalents of LiNCy2 (Cy is cyclo-hex-yl) resulted in the formation of tris-(di-cyclo-hexyl-amido)-zirconium chloride and the title compound, [Zr(C12H22N)4]. The latter is isotypic with its cerium(IV) analogue and crystallizes with three independent mol-ecules in the asymmetric unit. One mol-ecule is located about a twofold rotation axis, and the other two on fourfold inversion axes. In each mol-ecule, the ZrIV atom has a distorted tetra-hedral coordination environment. The crystal under investigation was twinned by inversion in a 1:1 ratio.

Diacetonitrile[N,N'-bis(2,6-diisopropyl-phenyl)ethane-1,2-diimine]dichloridochromium(II) acetonitrile solvate.

Project description:The title compound, [CrCl(2)(CH(3)CN)(2)(C(26)H(36)N(2))]·CH(3)CN, was synthesized by the reaction of CrCl(2)(THF)(2) with N,N'-bis-(2,6-diisopropyl-phen-yl)ethane-1,2-diimine in dichloro-methane/acetonitrile. The chromium center is coordinated by two N atoms of the chelating diimine ligand, two chloride ions in a trans configuration with respect to each other, and by two N atoms of two acetonitrile mol-ecules in a distorted octa-hedral geometry.

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.

(2,6-Diisopropyl-phen-yl)(2-thienylmethyl-ene)amine.

Project description:The title compound, C(17)H(21)NS, was prepared by the condensation of thio-phene-2-carbaldehyde with 2,6-diiso-propyl-aniline. It crystallizes with two mol-ecules in the asymmetric unit. The mol-ecules are inter-connected via a C-H?N hydrogen bond. The dihedral angles between the thio-phene and phenyl rings are 81.7?(7) and 85.5?(7)°.

Project description:In the title mol-ecule, C(26)H(26)N(2)O, the phenyl and phen-oxy rings form dihedral angles of 54.66?(7) and 84.83?(6)°, respectively, with the phthalazine mean plane. The crystal packing exhibits weak C-H?? inter-actions.

Zirconium Bis(Amido) Catalysts for Asymmetric Intramolecular Alkene Hydroamination.

Project description:In situ combination of diphosphinic amides and Zr(NMe(2))(4) results in the formation of chiral zirconium bis(amido) complexes. The complexes are competent catalysts for intramolecular asymmetric alkene hydroamintion, providing piperidines and pyrrolidines in up to 80% ee and high yield. This system utilizes an inexpensive zirconium precatalyst and readily prepared ligands and is the first asymmetric alkene hydroamination catalyst based upon a neutral zirconium bis(amido) complex.
