Abstract

C21H16N4O2,M r =356.4, crystallized from methanol in the orthorhombic space groupP212121,a=5.137(2),b=12.937(2),c=27.111(6) Å,V=1801.7(9) Å3,D x =1.314 g cm−3,Z=4, CuKα,μ=6.7 cm−1,F(000)=744,T=293K. The structure was solved with direct methods and refined by full-matrix least squares to a finalR=0.069 for 1303 observed reflections. The angles between triazine and adjacent phenyl rings planes are about 24° for anilino, 56 and 76° for phenoxy groups. The conjugation of the lone pair at the exocyclic O or N atoms is stronger with triazine than with the benzene π system because the correspondingtriazine-X(N, O) bonds are shorter by 0.04 to 0.07 Å than thebenzene-X.
