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

ABSTRACT: 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].

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 π-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]. ...[more]

[(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.

Chloridocyclo-hexyl[(1,2,5,6-η)-cyclo-octa-1,5-diene]platinum(II).

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.

(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).

(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°).

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.

[(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.

(18-Crown-6)potassium [(1,2,5,6-?)-cyclo-octa-1,5-diene][(1,2,3,4-?)-naph-tha-lene]-ferrate(-I).

Project description:The title salt, [K(C(12)H(24)O(6))][Fe(C(8)H(12))(C(10)H(8))], is the only known naphthalene complex containing iron in a formally negative oxidation state. Each (naphthalene)(1,5-cod)ferrate(-I) anion is in contact with one (18-crown-6)potassium cation via K?C contacts to the outer four carbon atoms of the naphthalene ligand (cod = 1,5-cyclo-octa-diene, 18-crown-6 = 1,4,7,10,13,16-hexa-oxacyclo-octa-deca-ne). When using the midpoints of the coordinating olefin bonds, the overall geometry of the coordination sphere around iron can be best described as distorted tetra-hedral. The naphthalene fold angle between the plane of the iron-coordinating butadiene unit and the plane containing the exo-benzene moiety is 19.2?(1)°.

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 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.

Dichlorido(?-cyclo-octa-1,5-diene)bis-(propane-nitrile-?N)ruthenium(II).

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.
