[(1,2,5,6-?)-Cyclo-octa-1,5-diene]bis-(4-methyl-phen-yl)platinum(II).

ABSTRACT: In the mononuclear title complex, [Pt(C(7)H(7))(2)(C(8)H(12))], the Pt(II) ion exhibits a square-planar coordination geometry defined by two methyl-phenyl ligands and the mid-points of the two ?-coordinated double bonds of cyclo-octa-1,5-diene. The two methyl-phenyl groups have a cis relationship with a C-Pt-C bond angle of 88.54?(18)° and a dihedral angle between the mean planes of the benzene rings of 83.87?(1)°. Each complex mol-ecule links to four symmetry-related ones through inter-molecular C-H?? inter-actions, forming a layer almost parallel to the bc plane.

In the mononuclear title complex, [Pt(C(7)H(7))(2)(C(8)H(12))], the Pt(II) ion exhibits a square-planar coordination geometry defined by two methyl-phenyl ligands and the mid-points of the two π-coordinated double bonds of cyclo-octa-1,5-diene. The two methyl-phenyl groups have a cis relationship with a C-Pt-C bond angle of 88.54 (18)° and a dihedral angle between the mean planes of the benzene rings of 83.87 (1)°. Each complex mol-ecule links to four symmetry-related ones through inter-molecula ...[more]

Bromido[(1,2,5,6-?)-cyclo-octa-1,5-diene]methyl-platinum(II).

Project description:In the title complex, [PtBr(CH(3))(C(8)H(12))], the Pt(II) ion is in a distorted square-planar environment defined by the Br and methyl C atoms and the mid-points of the two ?-coordinated double bonds of cyclo-octa-1,5-diene. As a result of the different trans influences of the Br atom and the methyl group, the Pt-C bonds trans to the methyl group [2.262?(11) and 2.261?(10)?Å] are longer than those trans to the Br atom [2.118?(8) and 2.138?(9)?Å].

[(1,2,5,6-?)-Cyclo-octa-1,5-diene]bis-(1-isopropyl-3-methyl-imidazolin-2-yl-idene)rhodium(I) tetra-fluorido-borate.

Project description:In the title compound, [Rh(C(8)H(12))(C(7)H(12)N(2))(2)]BF(4), the square-planar Rh complex cation and the BF(4) (-) anion are both bis-ected by a crystallographic twofold rotation axis. The Rh and B atoms lie on this axis and all others are in general positions. In the crystal, two unique C-H?F hydrogen-bonding inter-actions are present, which involve both imidazolin-2-yl-idene H atoms. They form two separate C(5) motifs, the combination of which is a rippled hydrogen-bonded sheet structure in the ab plane.

Crystal structure of chlorido-bis-[(1,2,5,6-η)-cyclo-octa-1,5-diene]iridium(I).

Project description:The title complex, [IrCl(C8H12)2], was synthesized directly from the reaction of IrCl3·3H2O with a large excess of cod (cod = cyclo-octa-1,5-diene) in alcoholic solvent. Large yellow needles were obtained by the slow cooling of a hot solution. Based on the positions of the chloride ligand and the mid-points of the four C=C bonds, the mol-ecule adopts a five-coordinate geometry that is midway between square pyramidal and trigonal bipyramidal. The material crystallizes in the ortho-rhom-bic space group Pbca with one mol-ecule per asymmetric unit in a general position and shows no significant inter-molecular inter-actions. Individual mol-ecules are aligned along [010], and these rows form a pseudo-hexa-gonal packing arrangement.

(Chlorido/bromido)[(1,2,5,6-η)-cyclo-octa-1,5-diene](4-isopropyl-1-methyl-1,2,4-triazol-5-yl-idene)rhodium(I).

Project description:A new triazole-based neutral RhI complex, [Rh(Cl0.846Br0.154)(C6H11N3)(C8H12)], has been synthesized and structurally characterized. The RhI atom has a distorted square-planar coordination environment, formed by a bidentate cyclo-octa-1,5-diene (COD) ligand, an N-heterocyclic carbene and a halide ligand that shows substitutional disorder (Cl:Br = 0.846:0.154). No significant inter-molecular inter-actions other than van der Waals forces are found in the crystal structure. Diffraction data indicated a two-component inversion twin with a ratio of 0.95 (5):0.05 (5).

Crystal structures of (?4-cyclo-octa-1,5-diene)bis(1,3-di-methyl-imidazol-2-yl-idene)iridium(I) iodide and (?4-cyclo-octa-1,5-diene)bis-(1,3-di-ethyl-imidazol-2-yl-idene)iridium(I) iodide.

Project description:The title complexes, (?4-cyclo-octa-1,5-diene)bis-(1,3-di-methyl-imidazol-2-yl-idene)iridium(I) iodide, [Ir(C5H8N2)2(C8H12)]I, (1) and (?4-cyclo-octa-1,5-di-ene)bis-(1,3-di-ethyl-imidazol-2-yl-idene)iridium(I) iodide, [Ir(C7H12N2)2(C8H12)]I, (2), were prepared using a modified literature method. After carrying out the oxidative addition of the amino acid l-proline to [Ir(COD)(IMe)2]I in water and slowly cooling the reaction to room temperature, a suitable crystal of 1 was obtained and analyzed by single-crystal X-ray diffraction at 100?K. Although this crystal structure has previously been reported in the Pbam space group, it was highly disordered and precise atomic coordinates were not calculated. A single crystal of 2 was also obtained by heating the complex in water and letting it slowly cool to room temperature. Complex 1 was found to crystallize in the monoclinic space group C2/m, while 2 crystallizes in the ortho-rhom-bic space group Pccn, both with Z = 4.

The central rhodium(I) atom has a distorted square-planar coordination environment, formed by a cyclo-octa-1,5-diene (COD) ligand, an N-heterocyclic carbene (NHC) ligand, and a chlorido ligand. The bond lengths are unexceptional. A weak inter-molecular non-standard hydrogen-bonding inter-action exists between the chlorido and NHC ligands.

(4-Butyl-1-methyl-1,2,4-triazol-5-yl-idene)[(1,2,5,6-η)-cyclo-octa-1,5-diene](tri-phenyl-phosphane)iridium(I) tetra-fluorido-borate.

Project description:A new triazole-based N-heterocyclic cationic carbene iridium(I) complex with a tetra-fluorido-borate counter-anion, [Ir(C8H12)(C7H13N3)(C18H15P)]BF4, has been synthesized and structurally characterized. The IrI atom of the cationic complex has an expected square-planar coordination environment with unexceptional bond lengths. There are several close F⋯H contacts between the cations and the anions in the range 2.36-2.58 Å, stabilizing the orientation of the out-sphere [BF4 -] counter-anion. In the crystal, C-H⋯π(ring) inter-actions are observed that orient the phenyl rings of the tri-phenyl-phosphane ligands.

Dichlorido(?-cyclo-octa-1,5-diene)bis-(triphenyl-phosphine)osmium(II).

Project description:The Os(II) atom in the title compound, [OsCl(2)(C(8)H(12))(C(18)H(15)P)(2)], is located on a crystallographic twofold axis and adopts a distorted octa-hedral coordination geometry.

The coordination is completed by the cyclo-octa-diene (COD) ligand with bonding to the two olefin double bonds. The C=C bond has a length of 1.403?(6)?Å, which is significntly longer than a free olefinic double bond (?1.34?Å).
