“…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).…”
