4,4-Dimethyl-3,4-dihydropyrido[2′,3′:3,4]pyrazolo[1,5-a][1,3,5]triazin-2-amine ethanol monosolvate

In the title compound, C10H12N6 center dot C2H5OH, the planarity of the heterocyclic system is slightly distorted at the triazine ring (r.m.s. deviation = 0.1191 angstrom), which adopts a conformation best described as intermediate between a flattened twisted boat and a half-boat with the tertiary Csp(3) atom at the bow. In the crystal, molecules form centrosymmetric dimers connected by N center dot center dot center dot H-O and O center dot center dot center dot H-N hydrogen bonds between the amino group H atom, the ethanol solvent molecule and the triazine N atom, making an R-4(4)(12) graph-set motif. The other H atom of the amino group and the H atom on the endocyclic N atom form N center dot center dot center dot H-N hydrogen bonds with the N atoms of the pyrazole and pyridine rings, respectively, linking the molecules into C(7) C(7) chains with the R-2(2)(8) binary graph-set motif running along [010].
