Structure of 5,5',6,6'-tetraphenyl-3,3'-bi-1,2,4-triazine

Abstract

The crystals were grown from an ethanol solution at 281 K.A crystal sealed in a glass capillary with N2 gas was used for the diffraction experiments. An anisotropic decay correction was applied and refinement was by full-matrix least-squares methods.Program used throughout the analysis: MolEN (Fair, 1990). Program used to solve structure: MULTAN11/82 (Main, Fiske, Hull, Lessinger, Germain, Declercq & Woolfson, 1982). Program used to draw figure: ORTEPII (Johnson, 1976 AbstractThe title compound (BDT) crystallizes in an s-trans conformation, the inversion center lying on the bond

5,5′,6,6′-Tetramethyl-3,3′-bi-1,2,4-triazine

“…The two 5,6-dimethyl-1,2,4-triazine parts of the molecule (I) are related by a crystallographic center of symmetry and possess the trans conformation, with the triazine rings being coplanar to within a 0.013 (2) Å maximum deviation from the mean plane. The geometry and conformation of (I) are very similar to those observed in the related structure of 5,5′,6,6′-tetraphenyl-3,3′-bi-1,2,4-triazine (Breu & Range, 1993).…”
