ABSTRACT: The title compound, C(20)H(12)Br(2)N(2), was prepared by the reaction of 1-(3-bromo-phen-yl)-2-(4-bromo-phen-yl)ethane-1,2-dione with o-phenyl-enediamine in refluxing ethanol. In the mol-ecule, all bond lengths and angles are within normal ranges. The dihedral angle between the two benzene rings is 34.89?(1)°. The dihedral angles between the benzene rings and the quinoxaline system are 57.23?(1) and 36.75?(1)°. The crystal packing is stabilized by van der Waals forces.

2,3-Bis(4-ethoxy-phen-yl)quinoxaline.

Project description:The title compound, C(24)H(22)N(2)O(2), was prepared by condensation of 1,2-bis-(4-ethoxy-phen-yl)ethane-1,2-dione and 1,2-diamino-benzene. The asymmetric unit contains one half-mol-ecule, close to a twofold axis. The plane of the quinoxaline ring is twisted with respect to the planes of the two ethoxy-phenyl ring systems, exhibiting dihedral angles of 39.95?(9)°. The crystal packing is dominated by weak C-H?? inter-actions. No classical hydrogen bonds or stacking inter-actions are observed.

Crystal structure of 2,3-bis-(4-methyl-phen-yl)benzo[g]quinoxaline.

Project description:The title compound, C26H20N2, was obtained during a search for new π-extended ligands with the potential to generate efficient phosphors with iridium(III) for organic light-emitting devices (OLEDs). The benzoquinoxaline ring system is almost planar (r.m.s. deviation = 0.076 Å). A pseudo-twofold rotation axis runs through the midpoints of the C2-C3 and C9-C10 bonds. The two phenyl rings are twisted relative to the benzoquinoxaline ring system, making dihedral angles of 53.91 (4) and 36.86 (6)°. In the crystal, C-H⋯π (arene) inter-actions link the mol-ecules, but no π-π inter-actions between aromatic rings are observed.

Crystal structures of 2,3-bis-(thio-phen-2-yl)pyrido[2,3-b]pyrazine and 7-bromo-2,3-bis-(thio-phen-2-yl)pyrido[2,3-b]pyrazine.

Project description:The crystal structures of 2,3-bis-(thio-phen-2-yl)pyrido[2,3-b]pyrazine, C15H9N3S2 (1), and 7-bromo-2,3-bis-(thio-phen-2-yl)pyrido[2,3-b]pyrazine, C15H8BrN3S2 (2), are discussed. Both mol-ecules crystallize in space group P21/c. In 1, the thienyl rings are inclined to the mean plane of the pyrido-pyrazine moiety by 6.16?(7) and 86.66?(8)°, where as in 2 the corresponding dihedral angles are 33.29?(11) and 19.84?(9)°. The pyrido-pyrazine moiety is relatively planar in 1 with the two rings being inclined to each other by 1.33?(7)°. In 2, however, the pyrido-pyrazine moiety is buckled with the corresponding dihedral angle being larger at 8.78?(10)°. In the crystal of 1, the packing creates inter-secting bilayers; the layering results from the pyrido-pyrazine moieties being engaged in offset ?-stacking, where the inter-planar distance is 3.431?(9)?Å with an offset 1.14?Å. In the crystal of 2, the mol-ecules pack head-to-head and are linked by a series of C-H?Br and C-H?N inter-molecular inter-actions, forming layers parallel to the ab plane.
