2,4,6-Tris-(4-fluoro-phen-yl)-2-(1-pyrid-yl)-boroxine.

ABSTRACT: Crystals of the title compound, C(23)H(17)B(3)F(3)NO(3), were obtained unintentionally by slow evaporation of a chloro-form solution of the preformed boroxine-pyridine adduct. The mol-ecule contains three fluoro-substituted benzene rings, each bonded to one of the three B atoms of a six-membered boroxine ring. A pyridyl ring is also bound to one of the B atoms through a Lewis acid-base inter-action. The binding of the pyridyl substituent causes the otherwise planar boroxine ring to twist, resulting in a maximum torsion angle within the ring of 17.6?(2)°.

2,4,6-Tris(2,4-dimethyl-phen-yl)-1,3,5-triazine.

Project description:Two virtually superimposable mol-ecules comprise the asymmetric unit of the title compound, C(27)H(27)N(3). The range of dihedral angles between the central 1,3,5-triazine ring and the attached benzene rings is 20.88?(14)-31.36?(14)°, and the shape of each mol-ecule is of a flattened bowl. The crystal packing features weak C-H?? bonds and ?-? inter-actions between triazine and benzene rings [centroid-centroid separations = 3.7696?(17) and 3.7800?(18)?Å] that result in the formation of supra-molecular layers in the ac plane. The crystal studied was a non-merohedral twin with a minor twin component of 20.7?(3)%.

Project description:The solvothermal reaction of Co(NO(3))(2) and 2,4,6-tris(4-pyridyl)-1,3,5-triazine in dimethyl-formamide/ethanol mixed solvent afforded the title coordination polymer, [Co(NO(3))(2)(C(18)H(12)N(6))](n), in which the Co(II) atom is seven-coordinated by pyridyl groups of three different ligands and two chelating nitrate anions. The complex displays a nano-sized porous metal-organic framework that belongs to a (10,3) topological network.

(Nitrato-?O)tris-[tris-(4-fluoro-phen-yl)phosphane-?P]copper(I).

Project description:In the title complex, [Cu(NO(3))(C(18)H(12)F(3)P)(3)], the ligating atoms define a distorted tetrahedon with the three tris-(4-fluoro-phen-yl)phosphane ligands in the basal positions and the nitrate ligand in the axial position. The intra-molecular ?-? inter-action [centroid-centroid distance = 3.6113?(11)?Å] between two of the 4-fluoro-phenyl groups is complemented by both C-H?F and C-H?O inter-actions with distances in the range 2.51-2.60?Å, resulting in a tight head-to-tail packing.

Chlorido[tris-(3-fluoro-phen-yl)phosphine]gold(I).

Project description:In the title gold complex, [AuCl(C(18)H(12)F(3)P)], the P-Au-Cl unit is nearly linear, with an angle of 178.13 (5)°. The three phosphine-substituted benzene rings make dihedral angles of 77.7 (3), 84.4 (3) and 77.4 (3)° with each other. Two of the three F atoms are disordered over two positions, with refined site occupancies of 0.591 (11):0.409 (11) and 0.730 (12):0.270 (12). In the crystal structure, mol-ecules are linked into a three-dimensional network by inter-molecular C-H⋯Cl and C-H⋯F hydrogen bonds.

1,3,5-Tris(4-meth-oxy-phen-yl)-1,3,5-triazinane-2,4,6-trione.

Project description:The complete mol-ecule of the title compound, C24H21N3O6, is generated by the application of threefold rotation symmetry about an axis perpendicular to the central ring. The mol-ecule exhibits a propeller-like shape. The dihedral angle between each benzene ring and the heterocyclic ring is 74.0 (1)°. The mol-ecules pack with no specific inter-molecular inter-actions between them. The SQUEEZE procedure in PLATON [Spek (2009 ▶). Acta Cryst. D65, 148-155] was used to model disordered solvent mol-ecules, presumed to be acetone; the calculated unit-cell data do not take into account the presence of these.

5-(4-Fluoro-phen-yl)-4-(4-pyrid-yl)-1,3-oxazol-2-amine.

Project description:In the crystal structure of the title compound, C(14)H(10)FN(3)O, the plane of the isoxazole ring makes dihedral angles of 35.72?(9) and 30.00?(9)°, respectively, with those of the 4-fluoro-phenyl and pyridine rings. The plane of the 4-fluoro-phenyl ring makes a dihedral angle of 45.85?(8)° with that of the pyridine ring. The crystal structure is stabilized by inter-molecular N-H?N hydrogen bonding. The two types of hydrogen bonds result in two chains, extending along the a axis, which are related by centres of symmetry.
