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

ABSTRACT: 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.

Project description:The title compound, C26H22N4 (I), was synthesized by C-H iridium-catalyzed borylation followed by Suzuki coupling.

These 2,3-di-methyl-quinoxalin-6-yl groups twist significantly out of the plane of the benzene ring. There are inter-molecular π-π inter-actions which result in a two-dimensional extended structure. The layers extend parallel to the ab plane and stack along the c axis.

Project description:The whole mol-ecule of the title porphyrin, C46H32N6O4·2C6H5NO2, which crystallized as a nitro-benzene disolvate, is generated by inversion symmetry. The porphyrin macrocycle is almost planar, the maximum deviation from the mean plane of the non-hydrogen atoms is 0.097 (2) Å. The aryl rings at the meso positions are inclined to this mean plane by 74.84 (6)° for the nitro-phenyl rings and 73.37 (7)° for the tolyl rings. In the crystal, the porphyrin mol-ecules are linked by C-H⋯O hydrogen bonds, forming chains along [100]. The solvent mol-ecules are also linked by C-H⋯O hydrogen bonds, forming chains along [100]. Inter-digitation of the p-tolyl groups along the c axis creates rectangular channels in which the solvent mol-ecules are located.

In the crystal packing of (II), the anions and cations are also linked by N-H⋯O and O-H⋯O hydrogen bonds involving also the water mol-ecules, giving a two-dimensional network across (001). The crystal structure is also stabilized by weak C-H⋯O and C-H⋯π inter-actions.
