Crystal structure of cyclo-bis-(?4-2,2-di-allyl-malonato-?(6) O (1),O (3):O (3):O (1'),O (3'):O (1'))tetra-kis-(triphenyl-phosphane-?P)tetra-silver(I).

ABSTRACT: In the tetra-nuclear mol-ecule of the title compound, [Ag4(C9H10O4)2(C18H15P)4], the Ag(I) ion is coordinated by one P and three O atoms in a considerably distorted tetra-hedral environment. The two 2,2-di-allyl-malonate anions bridge four Ag(I) ions in a ?4-(?(6) O (1),O (3):O (3):O (1'),O (3'):O (1')) mode, setting up an Ag4O8P4 core (point group symmetry -4..) of corner-sharing tetra-hedra. The shortest intra-molecular Ag?Ag distance of 3.9510?(3)?Å reveals that no direct d (10)?d (10) inter-actions are present. Four weak intra-molecular C-H?O hydrogen bonds are observed in the crystal structure of the title compound, which most likely stabilize the tetra-nuclear silver core.

Tetra-kis(triphenyl-phosphane-κP)silver(I) trifluoro-methane-sulfonate dichloro-methane monosolvate.

Project description:In the title compound, [Ag(C(18)H(15)P)(4)]CF(3)O(3)S·CH(2)Cl(2), the Ag atom is coordinated by four P atoms from four PPh(3) ligands. The P-Ag-P angles are in the range 108.02 (6)-110.15 (6)°, which confirms the distorted tetra-hedral environment around the Ag atom.

Crystal structure of an unknown tetra-hydro-furan solvate of tetra-kis-(μ 3-cyanato-κ(3) N:N:N)tetra-kis-[(triphenyl-phosphane-κP)-silver(I)].

Project description:In the title compound, [{[(C6H5)3P]Ag}4{NCO}4], a distorted Ag4N4-heterocubane core is set up by four Ag(I) ions being coordinated by the N atoms of the cyanato anions in a μ 3-bridging mode. In addition, a tri-phenyl-phosphine ligand is datively bonded to each of the Ag(I) ions. Intra-molecular Ag⋯Ag distances as short as 3.133 (9) Å suggest the presence of argentophilic (d (10)⋯d (10)) inter-actions. Five moderate-to-weak C-H⋯O hydrogen-bonding inter-actions are observed in the crystal structure, spanning a three-dimensional network. A region of electron density was treated with the SQUEEZE procedure in PLATON [Spek (2015). Acta Cryst. C71, 9-18] following unsuccessful attempts to model it as being part of disordered tetra-hydro-furan solvent mol-ecules. The given chemical formula and other crystal data do not take into account these solvent mol-ecules.

Tetra-kis(triphenyl-phosphane-?P)silver(I) tetra-fluorido-borate.

Project description:The title complex, [Ag(C(18)H(15)P)(4)]BF(4), was prepared by the reaction of silver(I) tetra-fluorido-borate and triphenyl-phosphane in the presence of 1,2-bis-(pyridin-2-yl)ethyl-ene. The Ag(I) atom is tetra-hedrally coordinated by four P atoms from triphenyl-phosphane (PPh(3)) ligands. Due to symmetry, the tetra-fluorido-borate anion is disordered over three positions (each with one third occupancy). The tetra-fluorido-borate anion does not coordinate to the Ag(I) atom.

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.

Tetra-kis(triphenyl-phosphane-?P)silver(I) trifluoro-acetate ethanol monosolvate.

Project description:In the title solvated salt, [Ag(C18H15P)4](CF3CO2)·C2H5OH, the Ag(I) atom is coordinated by four P atoms from triphenyl-phosphane ligands in a distorted tetra-hedral geometry. The anion and solvent are engaged in weak O-H?O hydrogen bonds. Of the four triphenyl-phosphane ligands, two each have an equally disordered phenyl ring while the Ag(I) atom is disordered over two positions in a 0.9595?(15):0.0405?(15) ratio and the trifluoro-acetate anion is equally disordered over two positions with respect to the lattice ethanol mol-ecule.

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.

[6-(4-Bromo-phen-yl)-2,2'-bipyridine-κN,N']bis-(triphenyl-phosphane-κP)copper(I) tetra-fluoridoborate.

Project description:The title compound, [Cu(C(16)H(11)BrN(2))(C(18)H(15)P)(2)]BF(4), is composed of one Cu(I) atom, one 6-(4-bromo-phen-yl)-2,2'-bipyridine (L) ligand, two triphenyl-phosphane mol-ecules and one tetra-fluoridoborate anion. The Cu(I) ion is four-coordinated in a distorted tetra-hedral configuration by two N atoms from L and two P atoms from triphenyl-phosphane ligands. In the L ligand, the two pyridine rings are not coplanar; the mean planes making a dihedral angle of 15.3 (5)°. In the crystal, the ions are linked by weak C-H⋯F inter-actions.

Bis[(1,10-phenanthroline-κ(2)N,N')bis-(triphenyl-phosphane-κP)copper(I)] nona-deca-oxidohexa-molybdate(VI).

Project description:The title compound, [Cu(C(12)H(8)N(2))(C(18)H(15)P)(2)](2)[Mo(6)O(19)], was obtained by co-crystallization of the mixed-ligand copper complex cation (1,10-phenanthroline)bis-(triphenyl-phos-phane)copper(I), [Cu(phen)(PPh(3))(2)](+), with the Lindquist polyanion [Mo(6)O(19)](2-). The asymmetric unit consists of half a Lindquist anion and one [Cu(phen)(PPh(3))(2)](+) cationic complex. In the cation, there are intra-molecular π-π inter-actions [centroid-centroid distances = 3.617 (2) and 3.7272 (18) Å]. This inorganic-organic adduct is connected by C-H⋯O hydrogen bonds, forming a two dimensional network lying in the ab plane. These networks are connected by C-H⋯π inter-actions into a three-dimensional structure.

Tricarbonylbis-(triphenyl-phosphane-κP)iridium(I) hexa-fluoridophosphate methanol monosolvate.

Project description:In the title compound, [Ir(C(18)H(15)P)(2)(CO)(3)]PF(6)·CH(3)OH, the Ir(I) atom is coordinated by two triphenyl-phosphine ligands in axial sites and three carbonyl ligands in the equatorial plane of a fairly regular trigonal bipyramid: the equatorial C-Ir-C angles range from 115.45 (9) to 126.42 (10)°. The small deviations from the ideal tetra-hedral geometry around the P atoms are illustrated by C-P-C angles ranging from 104.08 (9) to 106.46 (9)°. In the crystal, the mol-ecules are linked by weak C-H⋯F, C-H⋯O and C-H⋯π inter-actions.

Bis(methyl xanthato)-κS;κS:S'-(triphenyl-phosphane-κP)palladium(II).

Project description:The title compound, [Pd(C(2)H(3)OS(2))(2)(C(18)H(15)P)], features a palladium complex with a triphenyl-phosphane ligand and two xanthate ligands, one of them coordinates in a bidentate and the other in a monodentate fashion, giving rise to a slightly distorted square-planar coordination of the Pd(II) ion. As a result of this difference in the coordination modes, the C-S bond lengths are different, viz. 1.687 (2) and 1.692 (2) Å in the bidentate ligand and 1.723 (2) Å in the monodentate ligand, whereas the non-coordinating S atom has a C-S distance of 1.649 (2) Å. The crystal packing is stabilized by C-H⋯O inter-actions.
