4,4'-Oxybis(2,6-di-methyl-pyridinium) bis-(tri-fluoro-methane-sulfonate).

ABSTRACT: In the asymmetric unit of the title salt, C14H18N2O(2+)·2CF3O3S(-), the components are linked by two N-H?O and one C-H?O hydrogen bonds. The dipyridinium salt demonstrates a skew conformation based upon C-O-C-C torsion angles of 61.5?(3) and 15.1?(4)°. A C-O-C angle of 119.3?(2)° and C-O bond distances of 1.364?(3) and 1.389?(3)?Å are consistent with other dipyridyl ethers. The planes of the pyridyl rings exhibit a twist angle of 67.89?(8)°. One of the tri-fluoro-methane-sulfonate ions shows disorder of the F atoms [in a 0.52?(7):0.48?(7) occupancy ratio] and an O atom [0.64?(8):0.36?(8) occupancy ratio]. In the crystal, the components are linked by C-H?O inter-actions, which form chains along [101].

In the asymmetric unit of the title salt, C14H18N2O(2+)·2CF3O3S(-), the components are linked by two N-H⋯O and one C-H⋯O hydrogen bonds. The dipyridinium salt demonstrates a skew conformation based upon C-O-C-C torsion angles of 61.5 (3) and 15.1 (4)°. A C-O-C angle of 119.3 (2)° and C-O bond distances of 1.364 (3) and 1.389 (3) Å are consistent with other dipyridyl ethers. The planes of the pyridyl rings exhibit a twist angle of 67.89 (8)°.

Crystal structure of bis-(1-mesityl-1H-imidazole-?N 3)di-phenyl-boron tri-fluoro-methane-sulfonate.

Project description:The solid-state structure of bis-(1-mesityl-1H-imidazole-?N 3)di-phenyl-boron tri-fluoro-methane-sulfonate, C36H38BN4 +·CF3SO3 - or (Ph2B(MesIm)2OTf), is reported. Bis(1-mesityl-1H-imidazole-?N 3)di-phenyl-boron (Ph2B(MesIm)2 + ) is a bulky ligand that crystallizes in the ortho-rhom-bic space group Pbcn. The asymmetric unit contains one Ph2B(MesIm)2 + cationic ligand and one tri-fluoro-methane-sulfonate anion that balances the positive charge of the ligand. The tetra-hedral geometry around the boron center is distorted as a result of the steric bulk of the phenyl groups. Weak inter-actions, such as ?-? stacking are present in the crystal structure.

Bis(pyridinium) naphthalene-1,5-di-sulfonate dihydrate.

Project description:The asymmetric unit of the title organic salt, 2C(5)H(6)N(+)·C(10)H(6)O(6)S(2) (2-)·2H(2)O, consists of a pyridinium cation, half a naphthalene-1,5-disulfonate dianion and a water mol-ecule. The dianion has a crystallographically imposed centre of symmetry. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds link cations, anions and water mol-ecules into a three-dimensional network.

Bis(isonicotinamide-κN)silver(I) tri-fluoro-methane-sulfonate aceto-nitrile disolvate.

Project description:The central AgI atom of the title salt, [Ag(INAM)2](CF3SO3)·2CH3CN, where INAM is isonicotinamide (C6H6N2O), is twofold coordinated by the pyridine N atoms of two isonicotinamide ligands creating a slightly distorted linear mol-ecular geometry. The formation of polymeric chains {[Ag(INAM)2]+} n , held together by discrete hydrogen bonds through the amide group of the INAM ligand leaves voids for non-coordinating aceto-nitrile mol-ecules that inter-act the silver metal center via regium bonds.

{?-Bis(1-methyl-imidazol-2-yl)methane-?N:N}bis-{[(1-methyl-imidazol-2-yl)methane-?N,N]copper(I)} bis-(tri-fluoro-methane-sulfonate).

Project description:The title compound, [Cu(2)(C(9)H(12)N(4))(3)](CF(3)SO(3))(2), contains two Cu(I) ions, three bis-(1-methyl-imidazol-2-yl)methane (Me(2)BIM) ligands, and two trifluoromethanesulfonate anions in the asymmetric unit. Each Cu(I) ion has a distorted trigonal-planar geometry and is coordinated by two N atoms from the Me(2)BIM ligand and another N atom from the Me(2)BIM that acts as a bridging ligand, another N atom of the bridging Me(2)BIM being linked to the second Cu(I) ion. The imidazole rings of Me(2)BIM form intra-molecular ?-? stacking inter-actions [centroid-centroid distances = 3.445?(2) and 3.547?(2)?Å].

4-tert-Butyl-pyridinium chloride-4,4'-(propane-2,2-di-yl)bis-(2,6-di-methyl-phenol)-toluene (2/2/1).

Project description:In the title solvated salt, C9H14N(+)·Cl(-)·C19H24O2·0.5C7H7, two mol-ecules of 4,4'-(propane-2,2-di-yl)bis-(2,6-di-methyl-phenol) are linked via O-H⋯Cl hydrogen bonds to two chloride ions, each of which is also engaged in N-H⋯Cl hydrogen bonding to a 4-tert-butyl-pyridinium cation, giving a cyclic hydrogen-bonded entity centred at 1/2, 1/2, 1/2. The toluene solvent mol-ecule resides in the lattice and resides on an inversion centre; the disorder of the methyl group requires it to have a site-occupancy factor of 0.5. No crystal packing channels are observed.

Crystal structure of (2,2'-bipyrid-yl)[2,6-bis-(1-butyl-1H-benzimidazol-2-yl)pyridine]-chlorido-iridium(III) tri-fluoro-methane-sulfonate.

Project description:The title complex compound, [Ir(C27H29N5)Cl(C10H8N2)](CF3SO3)2, was synthesized for a study of iridium(III)/periodate redox systems in water. The coordination geometry of the complex can be best described as distorted octa-hedral, with an r.m.s. deviation of 8.8 (8)% from ideal octa-hedral rectangular geometry. In the crystal, C-H⋯O and C-H⋯F inter-actions between the complex cation and the tri-fluoro-methane-sulfonate anions are observed, as well as a C-H⋯Cl inter-molecular inter-action between neighboring complex cations. In addition, the benzimidazole ring systems display parallel-displaced π-π stacking with centroid-centroid distances of 3.585 (3)-3.907 (3) Å. One of the two tri-fluoro-methane-sulfonate anions is disordered over two orientations with an occupancy ratio of 0.582 (6):0.418 (6). The title complex was characterized using FT-IR, cyclic voltammetry/rotating disc electrode polarography, fluorescence spectrometry, high resolution mass spectrometry, CHN elemental analysis and 1H NMR spectroscopy.

Crystal structure at 100 K of bis-[1,2-bis-(di-phenyl-phosphan-yl)ethane]-nickel(II) bis-(tri-fluoro-methane-sulfonate): a possible negative thermal expansion mol-ecular material.

Project description:In the title salt, [Ni(C26H24P2)2](CF3SO3)2 or [Ni(dppe)2]2+·(OTf-)2 [dppe = 1,2-bis-(di-phenyl-phosphan-yl)ethane and OTf- = tri-fluoro-methane-sulfonate], the Ni atom (site symmetry ) has a square-planar geometry with the bidentate ligands chelating the metal. As a result of the steric hindrance of the phenyl rings, the counter-ions are blocked from the metal coordination sphere. The dynamic disorder of the anion existing at 296 K is reduced at 100 K and based on these two temperatures, negative thermal expansion behaviour is observed.

Di-μ-chlorido-bis-[(2,2':6',2''-terpyridine-κ3 N,N',N'')copper(II)] bis-(tri-fluoro-methane-sulfonate).

Project description:In the centrosymmetric title complex, [Cu2Cl2(C15H11N3)2](CF3O3S)2, the CuII metal center is fivefold coordinated by two chloride ions and three nitro-gen atoms of the terpyridine ligand in a distorted square-pyramidal geometry; two tri-fluoro-methane-sulfonate ions complete the outer coordination sphere. π-π stacking inter-actions between the pyridyl rings in adjacent mol-ecules contribute to the alignment of the complexes in columns along the a-axis. This structure represents the first example of a binuclear dication of formula [Cu(terpy)2Cl2]2+ with tri-fluoro-methane-sulfonate as counter-ions.

(5-Fluoro-4'-methyl-biphenyl-3-yl)(2,4,6-tri-methyl-phen-yl)iodo-nium tri-fluoro-methane-sulfonate.

Project description:In the title mol-ecular salt, C22H21FI(+)·CF3SO3 (-), the dihedral angle between the rings of the biphenyl group is 65.6?(1)°. The ring of the mesitylene group is inclined to the fluoro-benzene ring at an angle of 86.1?(3)° and the C-I-C bond angle is 97.0?(2)°. In the crystal, extremely short I?O contacts of 2.862?(5) and 2.932?(5)?Å occur, due to the strong electrostatic inter-actions between the I atom and two adjacent tri-fluoro-methane-sulfonate counter-ions. There are also C-H?F and C-H?? inter-actions present: together with the I?O bonds, these result in a three-dimensional network.

Crystal structure of 4,4'-bipyridine-1,1'-diium naphthalene-2,6-di-sulfonate dihydrate.

Project description:The title hydrated mol-ecular organic salt, C10H10N2 (2+)·C10H6O6S2 (2-)·2H2O, crystallized with half a bipyridinium cation, half a naphthalene-2,6-di-sulfonate anion and a water mol-ecule in the asymmetric unit. The whole cation and anion are generated by inversion symmetry, the inversion centers being at the center of the bridging C-C bond of the cation, and at the center of the fused C-C bond of the naphthalene group of the anion. In the crystal, the anions and cations stack alternately along the a axis with π-π inter-actions [inter-centroid distance = 3.491 (1) Å]. The anions are linked via O-H⋯O(sulfonate) hydrogen bonds involving two inversion-related water mol-ecules, forming chains along [10-1]. These chains are bridged by bifurcated N-H⋯(O,O) hydrogen bonds, forming a three-dimensional framework structure. There are also C-H⋯O hydrogen bonds present, reinforcing the framework structure.
