Crystal structure of di-methyl-formamidium bis-(tri-fluoro-methane-sulfon-yl)amide: an ionic liquid.

ABSTRACT: At 100?K, the title mol-ecular salt, C3H8NO+·C2F6NO4S2-, has ortho-rhom-bic (P212121) symmetry; the amino H atom of bis-(tri-fluoro-methane-sulfon-yl)amine (HNTf2) was transferred to the basic O atom of di-methyl-formamide (DMF) when the ionic liquid components were mixed. The structure displays an O-H?N hydrogen bond, which links the cation to the anion, which is reinforced by a non-conventional C-H?O inter-action, generating an R22(7) loop. A further very weak C-H?O inter-action generates an [001] chain.

Hydro-nium bis-(tri-fluoro-methane-sulfon-yl)amide-18-crown-6 (1/1).

Project description:The structure of the title compound, H3O+·C2F6NO4S2 -·C12H24O6 or [H3O+·C12H24O6][N(SO2CF3)2 -], which is an ionic liquid with a melting point of 341-343 K, has been determined at 113 K. The asymmetric unit consists of two crystallographically independent 18-crown-6 mol-ecules, two hydro-nium ions and two bis-(tri-fluoro-methane-sulfon-yl)amide anions; each 18-crown-6 mol-ecule complexes with a hydro-nium ion. In one 18-crown-6 mol-ecule, a part of the ring exhibits conformational disorder over two sets of sites with an occupancy ratio of 0.533 (13):0.467 (13). One hydro-nium ion is complexed with the ordered 18-crown-6 mol-ecule via O-H⋯O hydrogen bonds with H2OH⋯OC distances of 1.90 (6)-2.19 (7) Å, and the other hydro-nium ion with the disordered crown mol-ecule with distances of 1.85 (6)-2.36 (6) Å. The hydro-nium ions are also linked to the anions via O-H⋯F hydrogen bonds. The crystal studied was found to be a racemic twin with a component ratio of 0.55 (13):0.45 (13).

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

Project description: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].

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.

Crystal structure of 3β-acet-oxy-androsta-5,16-dien-17-yl tri-fluoro-methane-sulfon-ate.

Project description:The title compound, C22H29F3O5S [systematic name: (3S,8R,9S,10R,13S,14S)-10,13-dimethyl-17-(tri-fluoro-methylsulfon-yloxy)-2,3,4,7,8,9,10,11,12,13,14,15-dodeca-hydro-1H-cyclo-penta-[a]phenanthren-3-yl acetate], contains a fused four-ring steroidal system. Rings A and C adopt a chair conformation, while rings B and D adopt half-chair and envelope (with the fused CH atom as the flap) conformations, respectively. In the crystal, weak inter-molecular C-H⋯O inter-actions link the mol-ecules into layers parallel to the ab plane.

Crystal structure of tris-(1,10-phenanthroline-κ(2) N,N')iron(II) bis-[bis-(tri-fluoro-methyl-sulfon-yl)imide] monohydrate.

Project description:The crystal structure of the title complex, [Fe(C12H8N2)3][(CF3SO2)2N]2·H2O, is constructed by one octa-hedral [Fe(phen)3](2+) (phen = 1,10-phenanthroline) cation (point group symmetry 2), two Tf2N(-) [bis-(tri-fluoromethyl-sulfon-yl)imide] anions, and one water mol-ecule of crystallization (point group 2). The Fe-N bond lengths are indicative of a d (6) low-spin state for the Fe(II) ion in the complex. The dihedral angle between the phen ligands in the cation is 87.64 (6)°. The Tf2N(-) counter-anion is non-coordinating, with the -CF3 groups arranged in a trans fashion with respect to each other, leading to an anti,anti conformation of the -CF3 groups and -SO2N- moieties relative to the S-C bonds. The water mol-ecule of crystallization connects two O atoms of the Tf2N(-) anions through weak hydrogen bonds. C-H⋯O hydrogen-bonding inter-actions are also observed, consolidating the packing of the mol-ecules into a three-dimensional network structure.

Project description:The title ketenyl-idene, [Au3(C2O)(C26H35O2P)3](C2F6NO4S2), was obtained upon exposure of [2-(di-cyclo-hexyl-phosphino)-2',6'-dimeth-oxy-1,1'-biphen-yl]gold(I) bis-(tri-fluoro-methane-sulfon-yl)imide to acetic anhydride at elevated temperature. The ketenyl-idene bridge caps the tri-gold cluster. The title compound has provided crystals that upon analysis represent the first tri-gold ketenyl-idene with atomic distances indicative of bonding inter-action between the gold atoms.

Crystal structure of 2-[(di-chloro-methane)sulfon-yl]pyridine.

Project description:The asymmetric unit of the title compound, C6H5Cl2NO2S, contains two mol-ecules with similar conformations (r.m.s. overlay fit for the non-H atoms = 0.067?Å). Atoms attached to the pendent Csp (3)-S bond are arranged in a staggered conformation with one of the Cl atoms anti to the C atom in the aromatic ring [C-S-C-Cl torsion angles = 178.41?(11) and -176.70?(13)°]. In the crystal, mol-ecules are linked by C-H?N and C-H?O hydrogen bonds, generating a three-dimensional network, and weak aromatic ?-? stacking is also observed [centroid-centroid separation = 3.8902?(17)?Å].

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-?-acetato-?(4) O:O'-bis-[(1,10-phenanthroline-?(2) N,N')(tri-fluoro-methane-sulfonato-?O)copper(II)].

Project description:The complete molecule of the title compound, [Cu2(C2H3O2)2(CF3O3S)2(C12H8N2)2], is completed by the application of a twofold rotation and comprises two Cu(II) ions, each of which is penta-coordinated by two N atoms from a bidentate 1,10-phenanthroline (phen) ligand, two O atoms from acetate ligands and an O atom from a tri-fluoro-methane-sulfonate anion, forming a (4 + 1) distorted square-pyramidal coordination geometry. The Cu(II) ions are connected by two acetate bridges in a syn-syn configuration. The F atoms of the tri-fluoro-methane-sulfonate ligands are disordered, with site-occupation factors of 70 and 30. The molecular structure is stabilized by intra-molecular face-to-face ?-? inter-actions with centroid-centroid distances in the range 3.5654?(12)-3.8775(12)?Å. The crystal structure is stabilized by C-H?O interactions, leading to a three-dimensional lattice structure.
