Crystal structure of hexa-methyl 4,4',4'',4''',4'''',4'''''-[(1,3,5,2?5,4?5,6?5-tri-aza-triphosphinine-2,2,4,4,6,6-hexa-yl)hexa-kis-(-oxy)]hexa-benzoate.

ABSTRACT: The title compound, C48H42N3O18P3, achieved in a two-step synthesis, comprises a cyclo-triphosphazene core and six 4-meth-oxy-carbonyl-phen-oxy groups. Each P atom is attached to two substituents located up and down with respect to the plane of the phosphazene ring, the central P3N3 ring having a twist-boat conformation. The three O/P/O planes and five of the six benzene rings are nearly perpendicular to the mean plane through the phosphazene ring [dihedral angles = 82.98?(8)-88.92?(8)°], while the remaining benzene ring forms a dihedral angle of 25.72?(7)°. The crystal packing is stabilized by van der Waals inter-actions only.

Crystal structure of hexa-prop-2-en-1-yl 4,4',4'',4''',4'''',4'''''-[1,3,5,2λ(5),4λ(5),6λ(5)-tri-aza-triphosphinine-2,2,4,4,6,6-hexa-yl-hexa-kis-(-oxy)]hexa-benzoate.

Project description:In the title compound, C60H54N3O18P3, the central phosphazene ring is essentially planar, with an r.m.s. deviation of the six fitted atoms of 0.068 Å. The P-N bond lengths are within the narrow range 1.575 (2)-1.585 (2) Å, indicating the electrons are delocalized within the ring. The two ethenyl benzoate substituents on each P atom are located up and down with respect to the plane of the central P3N3 ring. The atoms of two terminal propenyl groups are disordered over two sets of sites, with refined site-occupancy ratios of 0.249 (12):0.751 (12) and 0.476 (9):0.524 (9). No intermolecular interactions are observed.

5,11,17,23,29,35-Hexa-tert-butyl-37,38,39,40,41,42-hexa-kis-(eth-oxy-carbonyl-meth-oxy)calix[6]arene acetonitrile disolvate.

Project description:In the title compound, C(90)H(120)O(18)·2CH(3)CN, the calix[6]arene has a 1,2,3-alternate conformation and possesses inversion symmetry. It crystallizes as an acetonitrile disolvate, with a half-mol-ecule of calix[6]arene and one mol-ecule of solvent in the asymmetric unit. In the crystal, the two solvent mol-ecules are enclosed in voids between the calix[6]arene mol-ecules. They form weak C-H?O hydrogen bonds involving an O atom of the lower rim substituent. The cavity of the calix[6]arene itself is enclosed by two opposite phenol rings, which are turned into the cavity due to the presence of a C-H?? inter-action. The calix[6]arene mol-ecule exhibits disorder of one substituent on its lower rim [occupancy ratio 0.897?(3):0.103?(3)].

4-Carb-oxy-pyridin-1-ium 2,4,5-tri-carb-oxy-benzoate monohydrate.

Project description:The title hydrated salt, C6H6NO2 (+)·C10H5O8 (-)·H2O, was isolated from the 1:1 cocrystallization of benzene-1,2,4,5-tetra-carb-oxy-lic acid and isonicotinic acid in ethanol solution. In the crystal, the cation is close to planar [r.m.s. deviation = 0.085?Å for the nine fitted atoms; the C-C-C-O(carbon-yl) torsion angle = -8.7?(4)°], but twists are evident in the anion, with all but the carb-oxy-lic acid group diagonally opposite the carboxyl-ate group being significantly twisted out of the plane of the benzene ring [C-C-C-O(carbon-yl) torsion angles = -118.1?(2), -157.6?(2), 4.3?(3) and 77.3?(3)°]. In the crystal, the ions and water mol-ecules are consolidated into a three-dimensional architecture by O-H?O and N-H?O hydrogen bonding along with C-H?O inter-actions.

Project description:In the title spiro-phosphazene derivative, C33H46N9OP3, the phosphazene and six-membered N/O rings are in flattened chair and twisted-boat conformations, respectively. The naphthalene ring system and the pyridine ring are oriented at a dihedral angle of 41.82?(4)°. In the crystal, weak C-H?O hydrogen bonds link the mol-ecules related by translation along the a axis into chains. C-H?? inter-actions aggregate these chains into layers parallel to the ab plane.

Crystal structures of 2,3,8,9,14,15-hexa-methyl-5,6,11,12,17,18-hexa-aza-tri-naphthyl-ene and 2,3,8,9,14,15-hexa-phenyl-5,6,11,12,17,18-hexa-za-tri-naphthyl-ene di-chloro-methane disolvate.

Project description:The crystal structures of two substituted HATN (hexa-aza-tri-naphthyl-ene) derivatives, namely 2,3,8,9,14,15-hexa-methyl- and 2,3,8,9,14,15-hexa-phenyl-5,6,11,12,17,18- hexa-zatri-naphthyl-ene (HATNMe6 and HATNPh6), are reported. Whereas the structure of the methyl-substituted derivative (HATNMe6) contains no solvent mol-ecules (C30H24N6), the hexa-phenyl-substituted structure (HATNPh6) contains two mol-ecules of di-chloro-methane (C60H36N6·2CH2Cl2). This class of planar bridging ligands is known for its electron-deficient systems and its ability to form π-π stacking inter-actions. Indeed, in both crystal structures strong π-π stacking inter-actions are observed, but with different packing features. The di-chloro-methane mol-ecules in the crystal structure of HATNPh6 are situated in the voids and are involved in C-H⋯N contacts to the nitro-gen atoms of the pyrazine units.

One N-H group makes an inter-molecular N-H?N hydrogen bond, forming centrosymmetric dimers, while the other N-H group makes an N-H?O hydrogen bond to the acetone solvent mol-ecule. The crystal was a two-component non-merohedral twin with ratio 0.811/0.189.

Project description:Assembly of the flexible dicarb-oxy-lic ligand 4-[2-(4-carboxyphenyl)-1,1,1,3,3,3-hexafluoropropan-2-yl]benzoate and 4,4'-bipyridine as co-ligand with Ag(I) ions resulted in the formation of the polymeric title compound, {[Ag(C(10)H(8)N(2))](C(17)H(9)F(6)O(4))}(n), in which the metal atoms are bridged by the 4,4'-bipyridine ligands, generating cationic chains extending along [010]. The dihedral angles between the benzene rings in the anion and the pyridine rings in the cation are 72.42?(9) and 9.36?(10)°, respectively. The mol-ecular conformation of the anion is stabilized by intra-molecular C-H?F hydrogen bonds. In the crystal, the anions inter-act with the cationic chains via C-H?O hydrogen bonds, forming layers parallel to (001), in which weak ?-? stacking inter-actions [centroid-centroid distances = 3.975?(3)-4.047?(3)?Å] involving the pyridine rings of adjacent 4,4'-bipyridine ligands are present. The planes are further assembled into a three-dimensional network by O-H?O hydrogen bonds.
