Low-temperature redetermination of 1,3-bis-(penta-fluoro-phen-yl)triazene.

ABSTRACT: The crystal structure of the title compound, (C(6)F(5))(2)N(3)H, is stabilized by N-H?N hydrogen bonding, forming centrosymmetric dimers organized in a herringbone motif. Important geometrical parameters are N-N = 1.272?(2) and 1.330?(2)?Å and N-N-N = 112.56?(15)°. The dihedral angle between C(6)F(5) groups is 21.22?(9)°. The room temperature structure was reported by Leman et al. (1993). Inorg. Chem.32, 4324-4336]. In the current determination, the data were collected to a higher ? angle, resulting in higher precision for the C-C bond lengths(0.001-0.005 versus 0.003?Å).

The crystal structure of the title compound, (C(6)F(5))(2)N(3)H, is stabilized by N-H⋯N hydrogen bonding, forming centrosymmetric dimers organized in a herringbone motif. Important geometrical parameters are N-N = 1.272 (2) and 1.330 (2) Å and N-N-N = 112.56 (15)°. The dihedral angle between C(6)F(5) groups is 21.22 (9)°.

1,3-Bis(2-ethoxy-phen-yl)triazene.

Project description:The title compound, C(16)H(19)N(3)O(2), exhibits a trans geometry about the N=N double bond in the triazene unit in the solid state, and individual mol-ecules are close to planar with r.m.s. deviations from planarity of 0.065 Å and 0.242 Å for the two independent molecules in the asymmetric unit. Distinct inter-molecular N-H⋯N hydrogen bonds lead to the formation of dimers with an R(2) (2)(8) graph-set motif. The steric demands of the eth-oxy groups in the ortho position prevent a coplanar arrangement of the two mol-ecules in the dimers and these instead consist of two inter-locked mol-ecules that are related by a non-crystallographic pseudo-twofold rotation axis. Weak C-H⋯π inter-actions between the CH groups and the aromatic phenyl rings also occur.

A new polymorph of 1,3-bis-(penta-fluoro-phen-yl)urea.

Project description:The title compound, C13H2F10N2O, has been previously described in the space group Pbca with Z = 8 [Jai-nhuknan et al. (1997 ?). Acta Cryst. C53, 455-457]. The current P212121 polymorph was obtained from a tetra-hydro-furan solution. The penta-fluoro-phenyl rings make dihedral angles of 50.35?(6) and 54.94?(6)° with the urea fragment, in close accord with those reported for the first polymorph. In the crystal, both of the N-H groups donate H atoms to the same carbonyl O atom, forming a one-dimensional mol-ecular array along the a axis. There are close contacts between perfluoro-phenyl C atoms within the array [3.228?(3)?Å] and halogen bonds are also observed between the arrays [F?F = 2.709?(2) and 2.7323?(18)?Å].

1,3-Bis(2-ethoxy-phen-yl)triazene methanol 0.33-solvate.

Project description:There are three independent mol-ecules of 1,3-bis-(2-ethoxy-phen-yl)triazene and a mol-ecule of methanol in the asymmetric unit of the title compound, C(16)H(19)N(3)O(2)·0.33CH(3)OH. Two mol-ecules related by a non-crystallographic pseudo-twofold rotation axis are linked via distinct inter-molecular N-H?N hydrogen bonds, leading to the formation of a dimer with an R(2) (2)(8) graph set. The third mol-ecule is connected to the methanol mol-ecule by O-H?N and N-H?O hydrogen bonds. There are a number of weak C-H?? inter-actions, with H?? distances ranging from 2.74 to 2.89?Å between the C-H groups and the aromatic benzene rings.

6-Benzyl-2-methyl-1,3-bis-(penta-fluoro-phen-yl)-1,3,6,2-triaza-alumocane.

Project description:In the title compound, [Al(CH(3))(C(23)H(15)F(10)N(3))], the Al(III) atom is coordinated in a distorted tetra-hedral geometry by three N atoms from the tridentate amine and by one C atom of the methyl substituent. Further, there is a short intra-molecular Al?F contact [2.5717?(11)?Å], leading to an overall distorted trigonal-bipyramidal coordination environment around Al(III).

(E)-1,3-Bis(2,3,4,5,6-penta-fluoro-phen-yl)prop-2-en-1-one.

Project description:In the title compound, C(15)H(2)F(10)O, the two perfluorinated arene rings are tilted at an angle of 66.08?(5)° with respect to each other. The olefinic double bond adopts an E configuration and the single bond between the olefinic and carbonyl double bonds has an s-trans conformation. The carbonyl group is not in a coplanar alignment with respect to the neighbouring arene ring (0.963?Å from aryl plane) while being coplanar with regard to the olefinic double bond (0.0805?Å from olefinic bond). The crystal packing does not feature significant hydrogen-bond-type or stacking inter-actions.

Project description:The dinuclear title complex, [Ti(2)(C(10)H(15))(2)(C(7)H(2)F(5)O)(4)O], features two Ti(IV) atoms bridged by an O atom. Each Ti atom is bonded to a ?(5)-penta-methyl-cyclo-penta-dienyl ring, two (penta-fluoro-phen-yl)methano-late anions and to the bridging O atom. The environment around each Ti atom can be considered as a distorted tetra-hedron.

1,5-Bis(penta-fluoro-phen-yl)-3-phenyl-pent-2-ene-1,5-dione.

Project description:In the title compound, C(23)H(8)F(10)O(2), the three arene rings are twisted one with respect to the other: the two perfluorinated arene rings are tilted to each other by an angle of 60.39?(7)°. They are inclined to the non-fluorinated phenyl unit by 38.85?(7) and 78.74?(7)°. The olefinic double bond adopts an E configuration. The carbonyl groups are not in a coplanar alignment with reference to the neighbouring arene rings. The crystal packing features a number of weak C-H?F inter-actions, which leads to the formation of a three-dimensional network.

1,3-Bis(4-fluoro-phen-yl)-N,N'-(propane-1,3-diyl-idene)dihydroxyl-amine.

Project description:The title compound, C(15)H(12)F(2)N(2)O(2), crystallizes with two mol-ecules (A and B) in the asymmetric unit. Both aromatic rings of both mol-ecules are disordered over two orientations [occupancy ratios of 0.768?(3):0.232?(3) and 0.770?(3):0.230?(3) for mol-ecule A and 0.789?(3):0.211?(3) and 0.789?(3):0.211?(3) for mol-ecule B]. The dihedral angles between the planes of the major and minor components of the disordered aromatic rings are 72.0?(4) and 71.2?(4)° for mol-ecule A, and 70.2?(4) and 71.5?(2)° for mol-ecule B. In the crystal, both mol-ecules form inversion dimers with R(2) (2)(6) ring motifs via pairs of inter-molecular O-H?N hydrogen bonds. The dimers are linked, forming zigzag C(7) chains along the c axis. Weak C-H?? inter-actions help to consolidate the packing.

1,3-Bis(2,3,5,6-tetra-fluoro-4-iodo-phen-oxy)-2,2-bis-[(2,3,5,6-tetra-fluoro-4-iodo-phen-oxy)meth-yl]propane.

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.
