Abstract
The compound 3,5-diamino-6-(2,3,5-trichlorophenyl)-1,2,4-triazine crystallizes with two methanol solvent molecules in the triclinic space group P1¯, with a = 7.372(4), b = 10.476(4), c = 11.863(11) Å, α = 72.18(5), β = 79.73(6), γ = 79.47(4)°. There is substantial distortion between the phenyl and triazine rings as illustrated by the value of the nonbonded angle C3t—C6t—C4 of 173.60° and the C4 atom being −0.4487 Å from the plane calculated for the triazine ring atoms. The lengths of the bonds of the triazine moiety suggest that there is a potential decrease in the degree of aromaticity of the ring. Comparisons are made between this structure, and other lamotrigine analog structures that have been reported.
