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

ABSTRACT: 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.

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.

(?-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-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.

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

Project description: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.

(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.

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.

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.

Project description: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.

Chlorido(chloro-diphenyl-phosphine-κP)(diphenyl-piperidinophosphine-κP)(η-penta-methyl-cyclo-penta-dien-yl)ruthenium(II).

Project description:The title compound, [Ru(C(10)H(15))Cl(C(12)H(10)ClP)(C(17)H(20)NP)], is a half-sandwich complex of Ru(II) with the chloro-diphenyl-phosphine ligand formed from the diphenyl-piperidinophosphine and chlorine of the precursor complex [Ru(η(5)-C(5)Me(5))(κ(1)P-Ph(2)PNC(5)H(10))Cl(2)] by an unexpected reaction with NaBH(4).

(Glycol-κO,O')nitros-yl(η-penta-methyl-cyclo-penta-dien-yl)ruthenium(II) bis-(tri-fluoro-methane-sulfonate).

Project description:The title compound, [Ru(C(10)H(15))(NO)(HOCH(2)CH(2)OH)](CF(3)SO(3))(2), possesses a three-legged piano-stool geometry around the Ru atom, with an average Ru-O distance of 2.120 (6) Å and an Ru-N-O angle of 159.45 (14)°. The ethyl-eneglycol ligand forms a non-planar metallacyclic ring by chelating the Ru atom via the O atoms. The O⋯O distances of 2.554 (2) and 2.568 (2) Å are indicative of hydrogen bonding between coordinated ethyl-eneglycol and outer-sphere trifluoro-methane-sulfonate fragments. The crystal packing is stabilized by ionic forces and several CH(3)⋯·F (2.585 and 2.640 Å) and CH(3)⋯O inter-actions (2.391, 2.678, 2.694 and 2.699 Å) between the penta-methyl-cyclo-penta-dienyl ligand and trifluoro-methane-sulfonate anion. There is noticeable short inter-molecular contact [2.9039 (16) Å], between an O atom of the SO(3) group and a C atom of the penta-methyl-cyclo-penta-dienyl ligand.
