Octa-carbonyldi-?(2)-hydrido-[?(3)-(1,3,5-trimethyl-phen-yl)phosphinidene](tri-phenyl-phosphane)-triangulo-triruthenium.

ABSTRACT: In the crystal structure of the title compound, [Ru(3)(C(9)H(11)P)H(2)(C(18)H(15)P)(CO)(8)], the triangular Ru(3) unit is capped with one mesitylphosphin-idene ligand. In the trigonal-pyramidal Ru(3)P core, one Ru(II) atom is coordinated by a triphenyl-phosphane ligand in a terminal fashion. Two hydride ligands bridge over two Ru-Ru bonds. These Ru-Ru bonds [2.9400?(4) and 2.9432?(4)?Å] are slightly longer than the nonhydride-bridged Ru-Ru bond [2.8146?(4)?Å]. The terminal triphenyl-phosphane ligand coordinates to the Ru(II) atom, which is involved in two hydride bridges.

Crystal structure of [1,2-bis-(di-phenyl-phosphan-yl)benzene]-hepta-carbonyldi-?-hydrido-(?3-2,4,6-tri-methyl-phenyl-phosphin-idene)-triangulo-triruthenium.

Project description:The title trinuclear ruthenium cluster, [Ru3(C30H24P2)(C9H11P)(CO)7(?-H)2], has a triangular Ru3 core that is capped with a mesitylphosphin-idene ligand, ?3-PMes (Mes = mesityl = 2,4,6-tri-methyl-phen-yl). The 1,2-bis-(di-phenyl-phosphan-yl)benzene mol-ecule acts as a bidentate phosphine ligand via two P atoms connecting to a single Ru atom. The title compound crystallizes with two independent mol-ecules in the asymmetric unit.

1,1,2,2,2,3,3,3-Octa-carbonyl-1,1,2,3-tetra-kis-(1,3,5-tri-aza-7-phosphatri-cyclo-[3.3.1.13,7]decane-κP)-triangulo-triosmium(0).

Project description:The title compound, [Os3(C6H12N3P)4(CO)8], crystallizes in the ortho-rhom-bic space group Pbca with Z = 8. The mol-ecule consists of a triangular triosmium(0) core surrounded by eight carbonyl ligands and four 1,3,5-tri-aza-7-phosphatri-cyclo-[3.3.1.13,7]decane (or PTA) ligands. One Os atom is coordinated by two PTA ligands and two CO ligands, while the other two Os atoms are each bonded to a single PTA ligand and three CO ligands. There is a small disorder associated with the Os3 unit so that a minor orientation has an occupancy of 2.17 (4)%. The title compound represents the first structurally characterized triangular Os3 carbonyl cluster with four monodentate tertiary phosphane ligands.

Hydrido(prolinato-κ(2) N,O)tris-(tri-methyl-phosphane-κP)iridium(III) hexa-fluorido-phosphate.

Project description:The title complex, [Ir(C5H8NO2)H(C3H9P)3]PF6, has two independent anion-cation pairs in the asymmetric unit. The geometry about each Ir(III) atom is pseudo-octa-hedral with a meridional arrangement of the P(CH3)3 ligands, N,O-bidentate coordination of prolinate and a hydride ligand trans to the prolinate N atom. The independent Ir(III) moieties are joined by N-H⋯O hydrogen bonds and the N-H⋯O bonding motif continues throughout the structure, creating an extended chain parallel to the c-axis direction. The methyl groups of one P(CH3)3 ligand are rotationally disordered over two sets of sites in a 0.62 (2):0.38 (2) ratio.

Trimethyl 2,2',2''-[1,3,5-triazine-2,4,6-tri-yltris-(aza-nedi-yl)]triacetate.

Project description:The title compound, C(12)H(18)N(6)O(6), was synthesized via nucleophilic substitution by reacting 2,4,6-trichloro-1,3,5-triazine with glycine methyl ester hydro-chloride in reflux (dried toluene) under anhydrous atmosphere. Individual mol-ecules self-assemble via strong N-H?O hydrogen bonds into supra-molecular double tapes running parallel to the [010] crystallographic direction. The close packing of supra-molecular tapes is mediated by geometrical reasons in tandem with a number of weaker N-H?O and C-H?N hydrogen-bonding inter-actions.

trans-Tetra-carbonyl-bis-(tri-phenyl-phosphane-κP)molybdenum(0).

Project description:The well known title compound, trans-[Mo(C18H15P)2(CO)4], has not been studied previously by X-ray crystallography, unlike its cis isomer. The complex possesses crystallographically imposed inversion symmetry, with the Mo atom residing on an inversion centre (1a Wyckoff position). The two tri-phenyl-phosphane groups are arranged in a staggered orientation. Each of the phenyl groups exhibits significantly different Mo-P-C-C torsion angles ranging from 2.6 (2) to 179.4 (1)°, most likely due to steric inter-actions based upon their positions relative to the carbonyl ligands.

[μ-Bis(di-o-tolyl-phosphan-yl)methane-1:2κP:P']nona-carbonyl-1κC,2κC,3κC-[diphen-yl(phenyl-sulfanylmeth-yl)phosphane-3κP]-triangulo-triruthenium(0) dichloro-methane 0.25-solvate.

Project description:In the title compound, [Ru(3)(C(29)H(30)P(2))(C(19)H(17)PS)(CO)(9)]·0.25CH(2)Cl(2), the atoms of the dichloro-methane solvent mol-ecule have a fractional site occupancy of 0.25; the dichloro-methane mol-ecule is disordered about an inversion centre. The bis-(di-o-tolyl-phosphan-yl)methane ligand bridges an Ru-Ru bond and the monodentate phosphane ligand bonds to the third Ru atom; its S-bonded phenyl ring is disordered over two orientations in a 0.53 (4):0.47 (4) ratio. All the P atoms are equatorial with respect to the Ru(3) triangle: each Ru atom also bears one equatorial and two axial terminal carbonyl ligands. The dihedral angles between the two benzene rings attached to each P atom of the diphenyl-phosphanyl ligand are 68.4 (2) and 71.5 (2)°. In the crystal, mol-ecules are linked into [001] chains via inter-molecular C-H⋯O hydrogen bonds. Weak inter-molecular C-H⋯π inter-actions also occur.

(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.

[(1,2,5,6-η)-Cyclo-octa-1,5-diene](1-ethyl-3-isopropyl-1,3-imidazol-2-yl-idene)(tri-phenyl-phosphane)rhodium(I) tetra-fluorido-borate.

Project description:A new N-heterocyclic cationic rhodium(I) complex with a tetra-fluorido-borate counter-anion, [Rh(C8H14N2)(C8H12)(C18H15P)]BF4, has been prepared and structurally characterized. The cationic complex exhibits a distorted square-planar environment around the rhodium(I) ion. Two connections are made from rhodium(I) to the carbon atom of an N-heterocylic carbene ligand and to the phospho-rus atom of a tri-phenyl-phosphane ligand. The remaining two coordination sites are made via a bidentate inter-action from the two olefinic bonds of cyclo-octa-diene to the rhodium(I) ion. The compound includes an out-sphere tetra-fluorido-borate counter-anion. Within the crystal of the compound exist several weak inter-molecular C-H⋯F inter-actions.

[μ-Bis(diphenyl-arsanyl)methane-1:2κAs:As']nona-carbonyl-1κC,2κC,3κC-[(4-methyl-sulfanylphen-yl)diphenyl-phosphane-3κP]-triangulo-triruthenium(0).

Project description:In the title triangulo-triruthenium compound, [Ru(3)(C(25)H(22)As(2))(C(19)H(17)PS)(CO)(9)], the bis-(diphenyl-arsanyl)methane ligand bridges an Ru-Ru bond and the monodentate phosphane ligand bonds to the third Ru atom. Both arsine and phosphane ligands are equatorial with respect to the Ru(3) triangle. In addition, each Ru atom carries one equatorial and two axial terminal carbonyl ligands. The three phosphane-substituted benzene rings make dihedral angles of 57.91 (19), 84.31 (15) and 59.37 (18)° with each other. The dihedral angles between the two benzene rings are 60.9 (2) and 85.40 (18)° for the two diphenyl-arsanyl groups. In the crystal, mol-ecules are linked into a three-dimensional framework by inter-molecular C-H⋯O hydrogen bonds. Weak inter-molecular C-H⋯π inter-actions stabilize the crystal structure.

Crystal structure of [1-(2,6-diiso-propyl-phen-yl)-2,4-bis-(di-methyl-amino)-5-tri-methyl-silyl-1,3,5-tri-aza-penta-dienyl-κ(2) N (1),N (5)](tri-phenyl-phosphane-κP)copper(I).

Project description:The title complex, [Cu(C21H38N5Si)(C18H15P)], was obtained from the one-pot reaction between (Dipp)N(Li)SiMe3 (Dipp = 2,6-diiso-propyl-phen-yl), Me2NCN, CuCl and PPh3. The Cu(I) atom has a distorted trigonal-planar coordination sphere. The tri-aza-penta-dienyl ligand acts as a κ(2)-donor. The N-Cu-N bond angle is 95.88 (14)°. In the tri-aza-penta-dienyl fragment, the C-N bond lengths are in the range 1.328 (5)-1.349 (5) Å, which indicates delocalization of the π-electrons in the NCNCN system.
