Dichlorido-1?Cl,3?Cl-hexa-kis-[1,1,2,2,3,3(??)-cyclo-penta-dien-yl]di-??-oxido-1:2?²O:O;2:3?²O:O-trizirconium(IV).

ABSTRACT: The title compound, [Zr?(C?H?)?Cl?O?], exists as discrete mol-ecules possessing a series of three Cp(2)Zr units (Cp is cyclo-penta-dien-yl) bridged by oxide ligands and end-capped by chloride ligands. The Cp planes in the central and terminal zirconocene units form dihedral angles of 53.3?(2) and 53.5?(2)°, respectively. The two Zr-O-Zr bridge angles are nearly linear and form a planar Zr?O? core. The mol-ecule bears C2 symmetry with the central Zr atom lying on a crystallographic twofold axis.

The title compound, [Zr₃(C₅H₅)₆Cl₂O₂], exists as discrete mol-ecules possessing a series of three Cp(2)Zr units (Cp is cyclo-penta-dien-yl) bridged by oxide ligands and end-capped by chloride ligands. The Cp planes in the central and terminal zirconocene units form dihedral angles of 53.3 (2) and 53.5 (2)°, respectively. The two Zr-O-Zr bridge angles are nearly linear and form a planar Zr₃O₂ core.

Project description:The title compound, [Hf(3)(C(6)H(7))(6)Cl(2)O(2)], is a trinuclear mol-ecule having two (MeCp)(2)HfCl units (MeCp is methyl-cyclo-penta-dien-yl) each connected to an (MeCp)(2)Hf unit by an oxide bridge. The two Hf-O-Hf bridges are nearly linear. The geometry of the three Hf atoms is tetra-hedral (assuming the MeCp group occupies one coordination site); the O-Hf-O angle is 99.8 (5)°. One of the Cl atoms is disordered, with site occupancies of 0.61 (7) and 0.39 (7).

Di-?(3)-oxido-di-?(2)-oxido-tetra-oxido-bis-(1,1,2,2-tetra-methyl-ethylenedicyclo-penta-dien-yl)-dimolyb-denum(IV)-dimolybdenum(VI) hexa-hydrate.

Project description:The title compound, [Mo(4)(C(16)H(20))(2)O(8)]·6H(2)O, is a centrosymmetric ansa-molybdocene complex in which two dinuclear [C(2)Me(4)(?(5)-C(5)H(4))(2)]Mo(?(2)-O)(2)MoO(2) units dimerize by forming two ?(3)-O bridges between three Mo atoms. The ansa-molybdocene [C(2)Me(4)(?(5)-C(5)H(4))(2)]Mo unit has a typical bent-sandwich metallocene structure with an inter-ring angle of 127.98?(8)°. The Mo atom in the bridging (?(2)-O)(?(3)-O)(2)MoO(2) group has a distorted trigonal-bipyramidal coordination. The Mo-(?(3)-O) and Mo-(?(2)-O) bond distances inside the units [2.0869?(14) and 2.1014?(15)?Å, respectively] are slightly longer than the Mo(-x + 1, -y + 1, -z)-(?(3)-O) bond distance between the units [1.9986?(14)?Å]. The solvent water mol-ecules together with complex O atoms form a network of O-H?O hydrogen bonds.

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.

Penta-carbonyl-2?C-chlorido-1?Cl-bis-[1(?)-cyclo-penta-dien-yl](?-1-oxido-ethyl-ene-1:2?O:C)chromium(0)zirconium(IV).

Project description:The title compound, [CrZr(C(5)H(5))(2)(C(2)H(3)O)Cl(CO)(5)], consists of two metal centres, with a (penta-carbonyl-chromium)oxymethyl-carbene group coordinating as a monodentate ligand to the zirconocene chloride. ?-Delocalization through the Zr-O-C=Cr unit is indicated by a short Zr-O distance [2.041?(3)?Å] and a nearly linear Zr-O-C angle [170.5?(3)°]. Mol-ecules are aligned with their mol-ecular planes (through Zr, Cl, carbene and Cr) parallel to the ab plane. C-H?Cl inter-actions result in zigzag chains of mol-ecules propagating parallel to the b axis.

Project description:The crystal structure of the title compound, [Hf(C10H15)2(C4H9)2], reveals two independent mol-ecules in the asymmetric unit. The diffraction experiment was performed with a racemically twinned crystal showing a 0.529?(5):0.471?(5) component ratio. Each Hf(IV) atom is coordinated by two penta-methyl-cyclo-penta-dienyl and two n-butyl ligands in a distorted tetra-hedral geometry, with the cyclo-penta-dienyl rings inclined to one another by 45.11?(15) and 45.37?(16)°. In contrast to the isostructural di(n-butyl)bis(? (5)-penta-methyl-cyclo-penta-dien-yl)zirconium(IV) complex with a noticeable difference in the Zr-butyl bonding, the Hf-Cbut-yl bond lengths differ from each other by no more than 0.039?(3)?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.
