Crystal structure of (3-carb-oxy-prop-yl)tri-phenyl-phospho-nium hexa-fluorido-phosphate.

ABSTRACT: In the title mol-ecular salt, C22H22O2P(+)·PF6 (-), the side chain of the cation adopts an anti-gauche conformation [P-C-C-C and C-C-C-C torsion angles = -179.11?(10) and -77.18?(16)°, respectively]. In the crystal, the cations are linked into carb-oxy-lic acid inversion dimers by pairs of O-H?O hydrogen bonds. Weak C-H?F and C-H?(F,F) hydrogen bonds connect the components into a three-dimensional network, but there are no aromatic ?-? stacking inter-actions.

In the title mol-ecular salt, C22H22O2P(+)·PF6 (-), the side chain of the cation adopts an anti-gauche conformation [P-C-C-C and C-C-C-C torsion angles = -179.11 (10) and -77.18 (16)°, respectively]. In the crystal, the cations are linked into carb-oxy-lic acid inversion dimers by pairs of O-H⋯O hydrogen bonds. Weak C-H⋯F and C-H⋯(F,F) hydrogen bonds connect the components into a three-dimensional network, but there are no aromatic π-π stacking inter-actions. ...[more]

(R)-(3-Carb-oxy-2-hy-droxy-prop-yl)tri-methyl-aza-nium chloride.

Project description:In the title salt (common name l-carnitine hydro-chloride), C(7)H(16)NO(3) (+)·Cl(-), the organic cation features a carb-oxy-lic part (-CO(2)H) having unambigous single- and double-bonds [1.336 (2), 1.211 (2) Å]. There is a large N-C-C bond angle [115.9 (1)°] for the C atom connected to the bulky trimethyl-amino substituent. In the crystal, the acid H atom forms a hydrogen bond to the chloride anion, whereas the hydroxyl H atom forms a longer hydrogen bond to the anion, generating a helical chain running along [001].

Crystal structure of benzyl-tri-phenyl-phospho-nium chloride monohydrate.

Project description:The title compound, Ph3(PhCH2)P(+)·Cl(-)·H2O, was obtained unintentionally as the product of an attempted synthesis of a silver di-thio-carbamate complex using benzyl-tri-phenyl-phospho-nium as the counter-ion. The asymmetric unit consists of a phospho-nium cation and a chloride anion, and a water mol-ecule of crystallization. In the crystal, the chloride ion is linked to the water mol-ecule by an O-H⋯Cl hydrogen bond. The three units are further linked via C-H⋯Cl and C-H⋯O hydrogen bonds and C-H⋯ π inter-actions, forming a three-dimensional structure.

Acetonyltri-phenyl-phospho-nium 2,3,5-tri-phenyl-tetra-zolium tetra-chlorido-cuprate(II).

Project description:The title compound, (C21H20OP)(C19H15N4)[CuCl4], was obtained by reacting CuCl2·2H2O with a mixture of one equivalent of acetonyltri-phenyl-phospho-nium chloride and one equivalent of 2,3,5-tri-phenyl-tetra-zolium chloride in aceto-nitrile. In the structure, the Cu centre in the dianion is bonded to four chloride ligands and adopts a distorted tetra-hedral geometry. The phospho-nium cation likewise adopts the expected tetra-hedral geometry. The tetra-zolium ring forms dihedral angles of 77.68 (10), 26.85 (11) and 66.48 (10)° with the planes of the benzene rings of the substituent groups. In the crystal, weak C-H⋯Cl hydrogen-bonding inter-actions involving both cations and the anion give rise to a three-dimensional supra-molecular structure.

[3-(Iodo-acetamido)prop-yl]triphenyl-phospho-nium tetra-phenyl-borate.

Project description:The title compound, C(23)H(24)INOP(+)·C(24)H(20)B(-), was prepared by treatment of 3-amino-propyl triphenyl-phospho-nium bromide hydrogen bromide with p-nitro-phenyl iodo-acetate at 203?K. The asymmetric unit contains a single cation and anion, which are linked in the crystal by inter-molecular N-H?? and inversion-related R(2) (2)(14) C-H?O inter-actions, which combine to form chains of cations and anions along the c axis.

[1,4-Phenyl-enebis(methyl-ene)]bis-(tri-phenyl-phospho-nium) bis-(tetra-fluoro-borate).

Project description:The crystal structure of the title salt, C(44)H(38)P(2) (2+)2BF(4) (-), consists of discrete dications inter-laced with the BF(4) (-) counter-ions. In each cation, both phospho-nium groups lie on the same side of the plane of the central benzene ring. The tetra-fluoro-borate anions are involved in intensive thermal motion, thus some B-F bond lengths [range 1.329 (6) to 1.391 (6) Å] deviate significantly from their standard values.

Crystal structure of tri-phenyl(vinyl)-phospho-nium tetra-phenyl-borate.

Project description:The title ionic salt, C21H20P(+)·C24H20B(-), crystallized with two independent vinyl-tri-phenyl-phospho-nium cations and two independent tetra-phenyl-borate anions per asymmetric unit. These four independent moieties contain nearly perfect tetra-hedral symmetry about their respective central C atoms. In the crystal, there are no ?-stacking or other inter-molecular inter-actions present.

Tetra-phenyl-phospho-nium iodide-1,3,5-tri-fluoro-2,4,6-tri-iodo-benzene-methanol (3/4/1).

Project description:The crystallization of a 1:1 molar solution of 1,3,5-tri-fluoro-2,4,6-di-iodo-benzene (TFTIB) and tetra-phenyl-phosponium iodide (TPPI) from methanol produced tetra-gonal needles of pure TPPI and tabular pseudo-hexa-gonal truncated bipyramids of the title compound, 3C24H20P(+)·3I(-)·4C6F3I3·CH4O or (TPPI)3(TFTIB)4·MeOH. The asymmetric unit is composed of six TPPI mol-ecules, eight TFTIB mol-ecules and two methanol mol-ecules, overall 16 constituents. The formation of the architecture is essentially guided by a number of C-I⋯I(-) halogen bonds (XB), whose lengths are in the range 3.276 (1)-3.625 (1) Å. Layers of supra-molecular polyanions are formed parallel to (10-1) wherein iodide anions function as penta-, tetra- or bidentate XB acceptors. The structure is not far from being P21/n, but the centrosymmetry is lost due to a different conformation of a single couple of cations and the small asymmetry in the formed supra-molecular anion. One methanol mol-ecule is hydrogen bonded to an iodide anion, while the second is linked to the first one via an O-H⋯O contact. This second methanol mol-ecule is more loosely pinned in its position than the first and presents very high anisotropic displacement parameters and a seeming shortening of the C-O bond length. The crystal studied was refined as a perfect inversion twin.

(±)-Bis(1-carb-oxy-2-phenyl-ethanaminium) hexa-fluoro-silicate(VI).

Project description:The asymmetric unit of the title fluoro-silicate salt, 2C(9)H(12)NO(2) (+)·SiF(6) (2-), consists of a phenylalaninium cation and half of a fluorosilicate anion, the Si atom being located on an inversion center. In the crystal, all of the F atoms act as hydrogen-bond acceptors and link the cations through different graph-set motifs, forming layers developing parallel to (100).

1,3-Bis(2,6-diisopropyl-anilino)-1-phenyl-butyl-ium hexa-fluorido-phosphate.

Project description:The cation of the title salt, C(34)H(45)N(2) (+)·PF(6) (-), is a protonated form of an unsymmetrical overcrowded β-imino-amine. The observed bond lengths [C-N = 1.326 (4)-1.341 (4) Å and C-C = 1.383 (4)-1.391 (4) Å] suggest significant delocalization within the π system of the N C C C N backbone.

Tetra-phenyl-phospho-nium hydrogen oxalate.

Project description:In the title compound, C(24)H(20)P(+)·C(2)HO(4) (-), two symmetry-independent ion pairs are present. The cations aggregate into puckered sheets via zigzag infinite chains of sixfold phenyl embraces and parallel fourfold phenyl embraces, while the anions form hydrogen-bonded chains between the sheets of cations. In the two independent oxalate anions, the angles between the normals to the two least-squares carboxyl-ate COO planes are unusually large, viz. 72.5 (1) and 82.1 (1)°.
