Crystal structure of 1,1,2,2-tetra-methyl-1,2-bis-(2,3,4,5-tetra-methyl-cyclo-penta-2,4-dien-1-yl)disilane.

ABSTRACT: The mol-ecular structure of the title compound, C22H38Si2, features a trans arrangement of the cyclo-penta-dienyl rings to avoid steric strain [C-Si-Si-C torsion angle = -179.0 (5)°]. The Si-Si bond length is 2.3444 (4) Å. The most notable inter-molecular inter-actions in the mol-ecular packing are C-H⋯π contacts that lead to the formation of wave-like supra-molecular chains along the b axis.

Di-μ2-chlorido-bis-[chlorido(η(5)-2,3,4,5-tetra-methyl-1-propyl-cyclo-penta-dien-yl)iridium(III)].

Project description:The asymmetric unit of the title complex, [Ir2Cl4(C12H19)2], a versatile starting material for the preparation of uniquely substituted penta-alkyl-cyclo-penta-dien-yl-iridium complexes, consists of an iridium(III) atom, a substituted cyclo-penta-dienyl ligand and two chlorine ligands. The full dimer is generated by an inversion center. In the dimer, the two Ir(III) atoms and two bridging Cl atoms form a perfectly planar ring. The two Ir(III) atoms and the two terminal Cl atoms also form a rigorous plane that is orthogonal [89.48 (3)°] to the Ir2Cl2 ring. The plane of the cyclo-penta-dienyl ligand forms a dihedral angle of 54.06 (7)° with respect to the Ir2Cl2 ring.

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.

Project description:The title compound, [Ru(2)(C(13)H(15)S)(2)(CO)(4)], is a centrosymmetric binuclear metal-carbonyl complex containing an Ru-Ru single bond [2.7511?(8)?Å]. Each Ru(I) atom is coordinated by two bridging carbonyl ligands, one terminal carbonyl ligand and one ?(5)-cyclo-penta-dienyl group. The complex has a trans conformation and the two cyclo-penta-dienyl ring planes are parallel. The crystal structure involves weak C-H?O hydrogen bonds.

(η-Benzophenone)(η-penta-methyl-cyclo-penta-dien-yl)ruthenium(II) tetra-phenyl-borate.

Project description:The structure of the title compound, [Ru(C(10)H(15))(C(13)H(10)O)](C(24)H(20)B), consists of discrete [Cp*Ru(II)benzophenone] cations and tetra-phenyl-borate anions (Cp* = penta-methyl-cyclo-penta-dien-yl). Tethering the Cp*Ru group to one aryl ring of benzophenone results in average values of 1.42 (1) and 1.38 (1) Å for the C-C bond lengths in the Ru-tethered and untethered phenyl rings, respectively. The dihedral angle between the benzene and phenyl rings of the benzophenone group is 50.5 (1)°.

[1-Dimethyl-silyl-2-phenyl-3-(η-tetra-methyl-cyclo-penta-dien-yl)-prop-1-en-1-yl-κC](η-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{η(5):η(1)-C(5)Me(4)(CH(2))}(η(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:In the structure of the title compound, [Fe{η(5)-C(5)(CH(3))(5)}(NCCH(3))(CO)(2)]BF(4), the arrangement of ligands around the Fe atom is in a pseudo-octa-hedral three-legged piano-stool fashion in which the penta-methyl-cyclo-penta-dienyl (Cp*) ligand occupies three apical coordination sites, while the two carbonyl and one acetonitrile ligands form the basal axes of the coordination. The Fe-N bond length is 1.924 (3) Å and the Fe-Cp* centroid distance is 1.722 Å.

trans-Di-μ-carbonyl-bis-{carbon-yl[η-2,3,4,5-tetra-methyl-1-(5-methyl-2-fur-yl)cyclo-penta-dien-yl]ruthenium(I)}(Ru-Ru).

Project description:In the crystal structure of the title compound, [Ru(2)(C(14)H(17)O)(2)(CO)(4)], each Ru(I) atom is connected to one end-on and two bridging carbonyl groups and one cyclo-penta-dienyl ring. The two Ru atoms are connected into binuclear complexes via two bridging carbonyl groups, forming four-membered rings which are located on centres of inversion. The Ru-Ru distance of 2.7483 (11) Å corresponds to a single bond. The two carbonyl groups in these binuclear complexes are trans-oriented.

(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.
