Tetra-phenyl-phospho-nium hydrogen oxalate.

ABSTRACT: 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)°.

Bis(tetra-phenyl-phospho-nium) tetra-sulfido-tungstate(VI).

Project description:The crystal structure of the title compound, (C(24)H(20)P)(2)[WS(4)], which was prepared under hydro-thermal conditions, contains tetra-phenyl-phospho-nium cations linked by supra-molecular inter-actions into chains running along the [110] and [10] directions. The [WS(4)](2-)anions, which lie on twofold axes, are located in the cavities created between the cation chains.

Bis(tetra-phenyl-phospho-nium) tetra-chlorido-cobaltate(II).

Project description:The title compound, (C24H20P)2[CoCl4], was prepared under hydro-thermal conditions. In the crystal, the tetra-phenyl-phospho-nium cations are linked by pairs of weak C-H⋯π inter-actions into supra-molecular dimers; the Co(II) cations lie on twofold rotation axes and the tetra-hedral [CoCl4](2-) anions are linked with the tetra-phenyl-phospho-nium cations via weak C-H⋯Cl hydrogen bonds.

Project description:The title compound, (C(24)H(20)P)(2)[MnI(4)]·(CH(3))(2)CO, prepared from the reaction of manganese powder, iodine and tetra-phenyl-phospho-nium iodide in acetone shows a tetra-hedral complex anion [Mn-I = 2.6868?(5)-2.7281?(4)?Å and I-Mn-I = 104.011?(13)-116.164?(15)°], two tetra-phenyl-phospho-nium cations and one mol-ecule of acetone.

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.

Tetra-phenyl-phospho-nium octa-hydro-triborate.

Project description:The structure of the title salt, C(24)H(20)P(+)·H(8)B(3) (-), at 120?(2)?K has triclinic (P1) symmetry with an unusual Z = 5, although there is pseudosymmetry observed with the tetraphenylphosphonium cations exhibiting I symmetry. One of the anions is disordered over two sets of sites with refined occupancies of 0.478?(11) and 0.522?(11).

[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.

Project description:The structure of the title compound, (C(24)H(20)P)(2)[Te(2)I(6)], is composed of discrete PPh(4) (+) cations and centrosymmetric [Te(2)I(6)](2-) anions.
