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-?(2) N (1),N (5)](tri-phenyl-phosphane-?P)copper(I).

ABSTRACT: 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 ?(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 ?-electrons in the NCNCN system.

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. ...[more]

Tri-methyl-phospho-nium trans-tetra-chlorido-bis-(tri-methyl-phosphane-κP)iridate(III).

Project description:The title compound, [HP(CH3)3][IrCl4{(H3C)3P}2], consists of a tri-methyl-phospho-nium cation and a tetra-chlorido-bis-(tri-methyl-phosphane)iridate(III) anion. The anion has an octa-hedral arrangement of ligands, with the tri-methyl-phosphane groups occupying trans positions. The Ir(III) atom sits on an inversion center with one P(CH3)3 ligand and two chloride ligands in the asymmetric unit. The tri-methyl-phospho-nium cation is disordered about a twofold rotation axis. The title compound is the first structurally characterized tetra-chlorido-bis-(phosphane)iridate complex.

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.

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-Oxido-bis-[hydridotris(tri-methyl-phosphane-κP)iridium(III)](Ir-Ir) bis-(tetra-fluorido-borate) dihydrate.

Project description:The title compound, [Ir2H2O(C3H9P)6](BF4)2·2H2O, was isolated from the reaction between [Ir(COD)(PMe3)3]BF4 and H2 in water (COD is cyclo-octa-1,5-diene). The asymmetric unit consists of one Ir(III) atom bonded to three PMe3 groups, one hydride ligand and half an oxide ligand, in addition to a BF4 (-) counter-ion and one water molecule of hydration. The single oxide ligand bridging two Ir(III) atoms is disordered across an inversion center with each O atom having a 50% site occupancy. Each Ir(III) atom has three PMe3 groups occupying facial positions, with the half-occupancy O atoms, a hydride ligand and an Ir-Ir bond completing the coordination sphere. The Ir-Ir distance is 2.8614 (12) Å, comparable to other iridium(III) metal-metal bonds. Two water mol-ecules hydrogen bond to two BF4 (-) anions in the unit cell.

Crystal structure of (1,3-di-methyl-thio-urea-κS)tris-(tri-phenyl-phosphane-κP)silver(I) acetate.

Project description:In the mononuclear title salt, [Ag(C3H8N2S)(C18H15P)3](CH3COO), the Ag(I) ion exhibits a distorted tetra-hedral coordination sphere defined by three P atoms from three tri-phenyl-phosphane ligands and one S atom from a 1,3-di--methyl-thio-urea ligand. In the crystal, the acetate anion is linked with the complex cation via duplex N-H⋯O hydrogen bonds [graph-set motif R (2) 2(8)].

cis-Bis(O-methyl-dithio-carbonato-κ(2) S,S')bis-(tri-phenyl-phosphane-κP)ruthenium(II).

Project description:In the title compound, [Ru(CH3OCS2)2(C18H15P)2], the Ru(II) atom is in a distorted octa-hedral coordination by two xanthate anions (CH3OCS2) and two tri-phenyl-phosphane (PPh3) ligands. Both bidentate xanthate ligands coordinate the Ru(II) atom with two slightly different Ru-S bond lengths but with virtually equal bite angles [71.57 (4) and 71.58 (3)°]. The packing of the complexes is assured by C-H⋯O and C-H⋯π inter-actions.

Chlorido(chloro-diphenyl-phosphine-κP)(diphenyl-piperidinophosphine-κP)(η-penta-methyl-cyclo-penta-dien-yl)ruthenium(II).

Project description:The title compound, [Ru(C(10)H(15))Cl(C(12)H(10)ClP)(C(17)H(20)NP)], is a half-sandwich complex of Ru(II) with the chloro-diphenyl-phosphine ligand formed from the diphenyl-piperidinophosphine and chlorine of the precursor complex [Ru(η(5)-C(5)Me(5))(κ(1)P-Ph(2)PNC(5)H(10))Cl(2)] by an unexpected reaction with NaBH(4). The complex has a three-legged piano-stool geometry, with Ru-P bond lengths of 2.2598 (5) Å for the chloro-phosphine and 2.3303 (5) Å for the amino-phosphine.

Tetra-μ3-iodido-tetra-kis-[(tri-n-butyl-phosphane-κP)copper(I)].

Project description:The title complex, [Cu4I4(C12H27P)4], crystallizes with six mol-ecules in the unit cell and with three independent one-third mol-ecule fragments, completed by application of the relevant symmetry operators, in the asymmetric unit. The tetranuclear copper core shows a tetrahedral geometry (site symmetry 3..). The I atoms also form a tetra-hedron, with I⋯I distances of 4.471 (1) Å. Both tetra-hedra show an orientation similar to that of a pair of self-dual platonic bodies. The edges of the I-tetra-hedral structure are capped to the face centers of the Cu-tetra-hedron and vice versa. The Cuface⋯I distances are 2.18 Å (averaged) and the Iface⋯Cu distances are 0.78 Å (averaged). As a geometric consequence of these properties there are eight distorted trigonal-bipyramidal polyhedra evident, wherein each trigonal face builds up the equatorial site and the opposite Cu⋯I positions form the axial site. As expected, the n-butyl moieties are highly flexible, resulting in large elongations of their anisotropic displacement parameters. Some C atoms of the n-butyl groups were needed to fix alternative discrete disordered positions.

Crystal structure of bis-[tetra-kis-(tri-phenyl-phosphane-κP)silver(I)] (nitrilo-tri-acetato-κ(4) N,O,O',O'')(tri-phenyl-phosphane-κP)argentate(I) with an unknown amount of methanol as solvate.

Project description:The structure of the title compound, [Ag(C18H15P)4]2[Ag(C6H6NO6)(C18H15P)], exhibits trigonal (P-3) symmetry, with a C 3 axis through all three complex ions, resulting in an asymmetric unit that contains one third of the atoms present in the formula unit. The formula unit thus contains two of the cations, one anion and disordered mol-ecules of methanol as the packing solvent. Attempts to refine the solvent model were unsuccessful, indicating uninter-pretable disorder. Thus, the SQUEEZE procedure in PLATON [Spek (2015 ▸). Acta Cryst. C71, 9-18] was applied, accounting for 670 electrons per unit cell, representing approximately 18 mol-ecules of methanol in the formula unit. The stated crystal data for M r, μ etc do not take these into account.

Crystal structure of bromido-nitro-syl-bis(tri-phenyl-phosphane-κP)nickel(II).

Project description:The asymmetric unit of the title complex, [NiBr(NO){P(C6H5)3}2], comprises two independent mol-ecules each with a similar configuration. The Ni(II) cation is coordinated by one bromide anion, one nitrosyl anion and two tri-phenyl-phosphane mol-ecules in a distorted BrNP2 tetra-hedral coordination geometry. The coordination of the nitrosyl group is non-linear, the Ni-N-O angles being 150.2 (5) and 151.2 (5)° in the two independent mol-ecules. In the crystal, mol-ecules are linked by weak C-H⋯Br hydrogen bonds and weak C-H⋯π inter-actions into a three-dimensional supra-molecular architecture.
