title: 6-Allyl-3-(6-chloro-3-pyridylmeth-yl)-6,7-dihydro-3H-1,2,3-triazolo[4,5-d]pyrimidin-7-imine.
abstract: The title compound, C(13)H(12)ClN(7), crystallizes with two independent mol-ecules in the asymmetric unit, each with similar geometries. The dihedral angles between the triazole and pyrimidine rings are 0.45 (9) and 1.00 (10)° in the two mol-ecules. A number of N-H⋯N hydrogen bonds co-operate with C-H⋯N contacts, forming a supra-molecular array in the ab plane. C-H⋯π inter-actions are also present. One of the vinyl groups was found to be disordered so that the C(H)=CH(2) atoms were resolved over two positions with the major component having a site occupancy factor of 0.539 (4).
