(?-Penta-methyl-cyclo-penta-dien-yl)(?-4-phenyl-butan-2-one)ruthenium(II) tetra-phenyl-borate.

ABSTRACT: The title compound, [Ru(C(10)H(15))(C(10)H(12)O)][B(C(6)H(5))(4)], crystallizes as discrete (?(5)-penta-methyl-cyclo-penta-dien-yl)Ru(?(6)-4-phenyl-butan-2-one)](+) cations and [BPh(4)](-) anions. In the cation, the non-H atoms of the butan-2-one group are approximately planar (r.m.s. deviation = 0.056?Å) and lie nearly perpendicular to the plane of the phenyl ring with a dihedral angle between the two planes of 69.3?(1)°. No significant C-H?O inter-actions are observed between the methyl and phenyl H atoms and the carbonyl O atom.

(?-Benzophenone)(?-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)°.

(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.

(η-Isopropyl N-phenyl-carbamate)(η-penta-methyl-cyclo-penta-dien-yl)ruthenium(II) tetra-phenyl-borate acetone monosolvate.

Project description:The title complex, [Ru(C(10)H(15))(C(10)H(13)NO(2))](C(24)H(20)B)·C(3)H(6)O, is related to the analogous O-methyl complex. The average Ru-C distance to the penta-methyl-cyclo-penta-dienyl (Cp*) group is 2.19 (3) Å, and 2.21 (1) Å to the ortho, meta and para C atoms of the arene ring. The Ru-C(ipso) bond length of 2.272 (3) Å is significantly longer, reflecting movement of the Ru atom away from the C atoms with electronegative substituents attached. The amide H atom in the cation forms an inter-molecular N-H⋯O hydrogen bond with the carbonyl O atom of the acetone solvent mol-ecule. A C-H⋯O inter-action also occurs.

Acetonitrile-dicarbon-yl(?-penta-methyl-cyclo-penta-dien-yl)iron(II) tetra-fluorido-borate.

Project description:In the structure of the title compound, [Fe{?(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.

[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.

[?-(Phenyl-ethyn-yl)cyclo-penta-dien-yl](?-tetra-phenyl-cyclo-butadiene)cobalt(I).

Project description:In the title compound, [Co(C(13)H(9))(C(28)H(20))], the Co atom is sandwiched between cyclo-penta-dienyl and cyclo-butadienyl rings that are inclined at a dihedral angle of 2.6?(3)°. The four phenyl rings are tilted with respect to the cyclo-butadienyl plane so that the C(4)Ph(4) unit constitutes a four-bladed propeller. The phenyl ring of the phenyl-alkyne substituent is inclined to the cyclo-penta-dienyl ring at an angle of 34.92?(18)°. The crystal structure is stabilized solely by C-H?? inter-actions which generate a three-dimensional network.

(η-Penta-methyl-cyclo-penta-dien-yl)(η-toluene)-ruthenium(II) hexa-fluorido-phosphate.

Project description:In the title complex, [Ru(C(7)H(8))(C(10)H(15))]PF(6), the cation lies on a mirror plane and the anion lies on an inversion center. The distance between the Ru atom and the centroid of the benzene ring is 1.706 (5) Å and the distance between the Ru atom and the cyclo-penta-dienyl ring is 1.811 (5) 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.

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.

Cyclo-hexyldimethyl-ammonium tetra-hydroxy-penta-borate.

Project description:The title compound, [C(8)H(18)N](+)·[B(5)O(6)(OH)(4)](-), has been synthesized under mild solvothermal conditions in the presence of N,N-dimethyl-cyclo-hexyl-amine acting as a template.

The [C(8)H(18)N](+) cations reside in the channels, inter-acting with the framework through N-H?O hydrogen bonds.
