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

ABSTRACT: 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 two triphenyl-phosphine ligands are trans to each other, while the two chlorine ligands are cis-disposed. 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).

Bis(acrylonitrile-?N)dichlorido(?-cyclo-octa-1,5-diene)ruthenium(II).

Project description:In the title complex, [RuCl(2)(C(8)H(12))(C(3)H(3)N)(2)], the metal ion is coordinated to centers of each of the double bonds of the cyclo-octa-1,5-diene ligand, to two chloride ions (in cis positions) and to two N-atom donors from two acrylonitrile mol-ecules that complete the coordination sphere for the neutral complex. The coordination about the Ru(II) atom can thus be considered octa-hedral with slight trigonal distortion. The three C atoms of one of the acrylonitrile ligands are disordered over two sets of sites in a 0.581?(13):0.419?(13) ratio.

Project description:In the title complex, [RuCl(2)(C(8)H(12))(C(3)H(5)N)(2)], the metal ion is coordinated to both double bonds of the cyclo-octa-1,5-diene ligand, two chloride ions (in cis positions) and two N-atom donors from two propane-nitrile mol-ecules that complete the coordination sphere for the neutral complex. The coordination around the Ru(II) atom can thus be considered as octa-hedral with slight trigonal distortion.

Bis(acetonitrile-?N)dichlorido(?-cyclo-octa-1,5-diene)ruthenium(II) acetonitrile monosolvate.

Project description:In the title Ru(II) complex, [RuCl(2)(C(8)H(12))(C(2)H(3)N)(2)]·CH(3)CN, the metal ion is coordinated to the centers of each of the double bonds of the cyclo-octa-diene ligand, to two chloride ions (in cis positions) and to two N-atom donors (from MeCN mol-ecules) that complete the coordination sphere for the neutral complex. The coordination about the Ru(II) atom can thus be considered to be octa-hedral with a slightly trigonal distortion. There is also one acetonitrile solvent mol-ecule per mol-ecule which is outside the coordination sphere of the ruthenium atom.

(η-Cyclo-octa-1,5-diene)diiodidoplatinum(II).

Project description:The monoclinic title complex, [PtI(2)(C(8)H(12))], characterized by a twisted cyclo-octa-diene ring, is similar to its Cl and Br ortho-rhom-bic homologues. The observed Pt-I bond distances of 2.6094 (5) and 2.6130 (5) Å are in the expected range for PtI(2) complexes. The C=C double bonds in the mol-ecule differ significantly [1.373 (10) and 1.403 (10) Å]. As expected for a platinum(II) complex, the Pt(II) atom is in a square-planar environment (ΣPt(α)= 359.71°).

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

Project description: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.

Bis[1,2-bis-(dimethyl-phosphino)ethane-κP,P']rhodium(I) dichlorido[(1,2,5,6-η)-1,5-cyclo-octa-diene]rhodium(I).

Project description:In the title complex, [Rh(C(6)H(16)P(2))(2)][RhCl(2)(C(8)H(12))], the asymmetric unit contains two [Rh(dmpe)(2)] [dmpe = 1,2-bis-(dimethyl-phosphino)ethane] half-cations, lying on inversion centers, and an [RhCl(2)(cod)](-) (cod = 1,5-cyclo-octa-diene) anion, wherein Rh is coordinated by two chloride ligands and two olefinic π-bonds of the cyclo-octa-diene ligand. The Rh atoms in the cations and anion exhibit square-planar coordination and are separated without any unusual inter-actions.

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].

Project description:In the title complex, [Pt(C(6)H(11))Cl(C(8)H(12))], the Pt(II) ion lies in a distorted square-planar environment defined by the Cl and cyclo-hexyl C atoms and the mid-points of the two π-coordinated double bonds of cyclo-octa-1,5-diene. As a result of the different trans influences of the Cl atom and the cyclo-hexyl group, the Pt-C bonds trans to the cyclo-hexyl group are longer than those trans to the Cl atom.

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.

Project description:In the title compound, [Ir(C(8)H(12))(C(7)H(12)N(2))(C(18)H(15)P)]BF(4)·CH(2)Cl(2), the Ir(I) atom has a square-planar conformation with normal bond lengths. One of the phenyl rings, and the solvent dichloro-methane mol-ecule, were refined using separate two part disorder models, each in an approximately 1:1 ratio.
