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.

(?-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)°.

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.

(Glycol-?O,O')nitros-yl(?-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.

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.

(?-Isopropyl N-phenyl-carbamate)(?-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.
