{2-[Bis(2,4-di-tert-butyl-phen-oxy)phosphan-yloxy-κP]-3,5-di-tert-butyl-phenyl-κC}[(1,2,5,6-η)-cyclo-octa-1,5-diene]rhodium(I) toluene monosolvate.

ABSTRACT: The reaction of (η(3)-all-yl)[(1,2,5,6-η)-cyclo-octa-1,5-diene]rhodium(I) with tris-(2,4-di-tert-butyl-phen-yl)phosphite in toluene produces the title compound, [Rh(C(42)H(62)O(3)P)(C(8)H(12))]·C(7)H(8), by spontaneous metallation at one of the nonsubstituted phenyl ortho-C atoms of the phosphite mol-ecule. The coordination geometry at the Rh(I) ion is distorted square-planar. The toluene solvent mol-ecule is disordered over two different orientations, with site-occupation factors of 0.810 (2) and 0.190 (2).

(Di-tert-butyl-phosphan-yl)bis-(diphenyl-phosphan-yl)phosphane.

Project description:The title phosphane, C(32)H(38)P(4) or (Ph(2)P)(2)P(P(t)Bu(2)), has a P atom that is linked to another three P atoms in a pyramidal configuration; the P-P distances in the range 2.2231 (7)-2.2446 (7) Å indicate that the P-P bonds are single bonds.

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.

Tris(tert-butyl isocyanide-κC)carbonylnickel(0).

Project description:The title compound, [Ni(C(5)H(9)N)(3)(CO)], was prepared from Ni(CO)(4) and a tenfold excess of tert-butyl isocyanide. It crystallizes with two symmetry-independent mol-ecules per asymmetric unit. The central Ni atom of each independent mol-ecule has a nearly perfect tetra-hedral coordination environment, comprising one carbon monoxide and three isocyanide ligands. The title compound is the first structurally characterized Ni(0) compound with a mixed CO/RNC coordination.

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.

Dichloridobis[(1S,1S',2R,2R')-(+)-1,1'-di-tert-butyl-2,2'-diphospho-lane-κP,P']ruthenium(II).

Project description:In the title compound, [RuCl(2)(C(16)H(32)P(2))(2)], the Ru(II) ion is situated on a twofold rotation axis, so the asymmetric unit contains one half-mol-ecule. The slightly distorted octa-hedral environment of the Ru center is formed by four P atoms [Ru-P = 2.4417 (6) and 2.4544 (6) Å] from two different (1S,1S',2R,2R')-TangPhos ligands [(1S,1S',2R,2R')-TangPhos = (1S,1S',2R,2R')-(+)-1,1'-di-tert-butyl-2,2'-diphospho-lane] and two Cl atoms [Ru-Cl = 2.4267 (5) Å].

Di-μ-iodido-bis-[(diethyl ether-κO)(η-1,3-di-tert-butyl-cyclo-penta-dien-yl)ytterbium(II)].

Project description:The half-sandwich title compound, [Yb(2)(C(13)H(21))(2)I(2)(C(4)H(10)O)(2)], crystallizes as a centrosymmetric dimer. The Yb atom is coordinated in a three-legged piano-stool geometry by a cyclo-penta-dienyl ring, two I anions and the O atom of a diethyl ether mol-ecule. The central Yb(2)I(2) core is an approximate square.

[2-Butyl-4-(4-tert-butyl-benz-yl)-1,2,4-triazol-3-yl-idene]chlorido[(1,2,5,6-?)-cyclo-octa-1,5-diene]iridium(I).

Project description:In the title compound, [IrCl(C(8)H(12))(C(17)H(25)N(3))], the Ir(I) ion has a distorted square-planar coordination geometry. The N-heterocyclic carbene ligand has an extended S-shaped conformation. The butyl group was refined using a two-part 1:1 disorder model. In the crystal, three unique weak C-H?Cl contacts are present. Two of these form a motif described as R(2) (1)(6) in graph-set notation, while a third forms an R(2) (2)(8) motif about a crystallographic inversion center. The result is a chain structure which extends parallel to the crystallographic a axis.

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.

(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.
