(Tris{2-[2-(2,3,5,6-tetra-fluoro-4-iodo-phen-oxy)eth-oxy]eth-yl}amine)-potassium iodide.

ABSTRACT: The title adduct, [K(C30H24F12I3NO6)]I, gives an extended tape of cations linked through I?I(-) halogen bonds (XBs), two of them being quite short and one quite long. In the structure, the cation is hosted in a cavity formed by the arms of the podand which presents a closed conformation wherein two tetra-fluoro-iodo-benzene rings are near parallel [dihedral angle = 15.8?(4)°; centroid-centroid distance = 3.908?(5)?Å] and the third ring is closer to orthogonal [dihedral angles = 66.28?(14) and 75.20?(19)°] to the other two rings. The coordination sphere of the K(+) cation is composed of the six O atoms, the N atom and an F atom in the ortho position of one of the rings.

The title adduct, [K(C30H24F12I3NO6)]I, gives an extended tape of cations linked through I⋯I(-) halogen bonds (XBs), two of them being quite short and one quite long. In the structure, the cation is hosted in a cavity formed by the arms of the podand which presents a closed conformation wherein two tetra-fluoro-iodo-benzene rings are near parallel [dihedral angle = 15.8 (4)°; centroid-centroid distance = 3.908 (5) Å] and the third ring is closer to orthogonal [dihedral angles = 66.28 (14) and 75 ...[more]

Project description:In the crystal structure of the title compound, C29H8F16I4O4, short I?I and I?F contacts, which can be understood as halogen bonds (XBs), represent the strongest inter-molecular inter-actions, consistent with the presence of I and F atoms, and the absence of H atoms, at the periphery of the mol-ecule. In addition, ?-? stacking inter-actions between tetra-fluoro-iodo-phenyl (TFIP) groups and five short F?F inter-actions are present.

Project description:The reaction of 2-amino-ethanol and iodo-penta-fluoro-benzene in the presence of K(2)CO(3) gave the title compound, C(8)H(6)F(4)INO, in high yield. The structure is characterized by double layers of mol-ecules linked by O-H?O and N-H?O hydrogen bonds, and linear C-I?F [I?F = 3.049?(2)?Å] and bent C-I?I [I?I = 3.9388?(7)?Å] inter-actions between pairs of nearly parallel iodo-tetra-fluoro-phenyl groups. No O?I or N?I halogen bonding is found.

Tris(2-benzamido-eth-yl)ammonium tetra-fluoro-borate.

Project description:In the title compound, C(27)H(31)N(4)O(3) (+)·BF(4) (-), the central N atom is protonated. The three arms form a pocket and one amidic O atom accepts an inter-molecular hydrogen bond with the protonated amine. The tetra-fluoro-borate anion is outside the cavity and is hydrogen bonded to one amide N atom. Adjacent organic cations are connected by a pair of N-H⋯O hydrogen bonds, forming a chain.

The 1:1 co-crystal of triphen-yl(2,3,5,6-tetra-fluoro-benz-yl)phospho-nium bromide and 1,1,2,2-tetra-fluoro-1,2-di-iodo-ethane.

Project description:The title compound, C25H18F4P(+)·Br(-)·C2F4I2, is a 1:1 co-crystal of triphen-yl(2,3,5,6-tetra-fluoro-benz-yl)phospho-nium (TTPB) bromide and 1,1,2,2-tetra-fluoro-1,2-di-iodo-ethane (TFDIE). The crystal structure consists of a framework of TTPB cations held together by C-H?Br inter-actions. In this framework, infinite channels along [100] are filled by TFDIE mol-ecules held together in infinite ribbons by short F?F [2.863?(2)-2.901?(2)Å] inter-actions. The structure contains halogen bonds (XB) and hydrogen bonds (HB) in the bromide coordination sphere. TFDIE functions as a monodentate XB donor as only one I atom is linked to the Br(-) anion and forms a short and directional inter-action [I?Br(-) 3.1798?(7)?Å and C-I?Br(-) 177.76?(5)°]. The coordination sphere of the bromide anion is completed by two short HBs of about 2.8?Å (for H?Br) with the acidic methyl-ene H atoms and two longer HBs of about 3.0?Å with H atoms of the phenyl rings. Surprisingly neither the second iodine atom of TFDIE nor the H atom on the tetra-fluoro-phenyl group make any short contacts.

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.

(2,3,5,6-Tetra-fluoro-phenolato)[5,10,15,20-tetra-kis-(4-meth-oxy-phen-yl)porphyrinato]iron(III) cyclo-hexane monosolvate.

Project description:The title compound, [Fe(C6HF4O)(C48H36N4O4)]·C6H12, represents a five-coordinate iron(III) porphyrin complex in a square-pyramidal geometry with a tetra-fluoro-phenolate anion as the axial ligand.

(2,3,5,6-Tetra-fluoro-phenolato-?O)(5,10,15,20-tetra-phenyl-porphyrinato)iron(III).

Project description:The title compound, [Fe(C44H28N4)(C6HF4O)], is a porphyrin complex with iron(III) in fivefold coordination with a tetra-fluoro-phenolate group as the axial ligand. The Fe atom and the phenolate ligand are disordered across the porphyrin ring with the two phenolates appearing to be roughly related by a center of symmetry. The occupancies of the two phenolate groups refined to 0.788?(3) for the major component and 0.212?(3) for the minor component. The structure shows extraordinary Fe displacements of 0.488?(4) (major) and 0.673?(4)?Å (minor) from the 24-atom mean plane of the porphyrin. The Fe-Np distances range from 2.063?(4) to 2.187?(6)?Å and the Fe-O distances are 1.903?(5)?Å for major component and 1.87?(2)?Å for minor component. The four phenyl groups attached to the porphyrin ring form dihedral angles of 63.4?(4), 49.6?(4), 62.4?(4), and 63.3?(4)° (in increasing numerical order) with the three nearest C atoms of the porphyrin ring. The major and minor component phenolate groups form dihedral angles of 24.9?(4)° and 24.8?(4)°, respectively, with the four porphyrin N atoms. The Fe?Fe distance between the two iron(III) atoms of adjacent porphyrin mol-ecules is 6.677?(3)?Å. No close inter-molecular inter-action was observed. The crystal studied was twinned by inversion, with a major-minor component ratio of 0.53?(3):0.47?(3).

Project description:In the title compound, C(15)H(7)Cl(2)F(6)NO(2), the conformation of the N-H bond in the amide segment is anti to the C=O bond and the dihedral angle between the two benzene rings is 78.6?(3)°. The terminal -CHF(2) group is disordered over two orientations in a 0.67:0.33 ratio. In the crystal, the mol-ecules are linked by N-H?O hydrogen bonds, generating C(4) chains propagating in [100].

Zwitterionic form of tris-({[5-(4-meth-oxy-phenyl-azo)salicyl-idene]amino}-eth-yl)amine.

Project description:THE TITLE COMPOUND (SYSTEMATIC NAME:2-{[2-(bis-{2-[({2-hy-droxy-5-[(4-meth-oxy-phen-yl)diazen-yl]phen-yl}methyl-idene)amino]-eth-yl}amino)-eth-yl]aza-niumylidenemeth-yl}-4-[(4-meth-oxy-phen-yl)diazen-yl]phenolate), C(48)H(48)N(10)O(6), exists as a zwitterion in the solid state. The three arms of the tripodal mol-ecule are located close to each other and an intra-molecular hydrogen bond occurs in each arm (O-H?N in two arms and N-H?O in the zwitterionic arm). The dihedral angles between the aromatic rings in the three arms are 16.36?(14), 23.94?(14) and, for the zwitterionic arm, 37.14?(14)°. In the crystal, a weak inter-moleclar N-H?O hydrogen bond occurs.
