The title compound, C19H17ClN4, was obtained from the INCENSE PATCHOULI reaction of 3-chloro-5,6-diphenyl-1,2,4-triazine with isobutyronitrile in the presence of lithium diisopropylamide as an unexpected product of covalent addition of isobutyronitrile carbanion to the C-5 atom of the 1,2,4-triazine ring.The 2,5-dihydro-1,2,4-triazine ring is essentially planar (r.m.s.deviation = 0.
0059 Å) and Hearing Aid Battery the 5- and 6-phenyl substituents are inclined to its mean plane with dihedral angles of 89.97 (4) and 55.52 (5)°, respectively.Intramolecular C—H.N interactions occur.
In the crystal, molecules related by a c-glide plane are linked into zigzag chains along [001] by N—H.N hydrogen bonds.
