Abstract:
In the title compound, C(9)H(12)Cl(2)N(4), the piperidine ring adopts a chair conformation. The electron delocalization of the molecule is indicated by the similar C⋯N distances within the triazine ring and by the double-bond character of the C=N triazine-piperidine connectivity. Weak intra-molecular C-H⋯N hydrogen bonds link the two rings within the mol-ecule, which exhibits a pseudo-mirror plane if the methyl group is ignored. π-π Inter-actions between pairs of triazine rings with stacking distances of 3.521 (7) Å are observed in the crystal structure, generated via crystallographic inversion centers.
