The title compound, C13H12ClN7, crystallizes with two independent molecules in the each with similar geometries. The dihedral angles between the triazole and pyrimidine rings are 0.45 (9) and 1.00 (10)° in the two molecules. A number of N—H⋯N hydrogen bonds co-operate with C–H⋯N contacts, forming a supramolecular array in the ab plane. C—H⋯π interactions are also present. One of the vinyl groups was found to be disordered so that the C(H)=CH2 atoms were resolved over two positions with the major component having a site occupancy factor of 0.539 (4).

Allylamine (1 mmol) in anhydrous acetonitrile (4 ml) was added dropwise to a solution of ethyl-N-3-((6-chloropyridin-3-yl)methyl)-5-cyano-3H-1,2,3- triazol-4-yl-formimidate (1 mmol) in anhydrous acetonitrile (8 ml) at room temperature. The mixture was stirred until the reaction was complete (by thin layer chromatography) and the solution concentrated under vacuum. The residue was recrystallized from anhydrous ethanol to give (I) (yield 87%). Colourless crystals were grown from a dichloromethane and petroleum ether (1:3 v/v) solution of (I).
H atoms were placed in calculated positions, with C—H distances in the range 0.93–0.97 Å and N—H distances of 0.86 Å, and included in the final cycles of
using a riding-model approximation, with Uiso(H) = 1.2–1.5Ueq(carrier atom). A rotating group model was used for the methyl groups. Disorder was noted in the C24-C26 vinyl substituent in that two positions were resolved for the C25 atom. From the major component had a site occupancy factor = 0.539 (4).Data collection: SMART (Bruker, 2000); cell

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

1,2,3-Triazolo[4,5-d]pyrimidines, i.e. 8-azapurines (Albert, 1986), have attracted attention because some of these derivatives exhibit anti-viral (Slusarkchyk & Zahler, 1989), anti-tumour (Slusarkchyk & Zahler, 1989; Vince & Hua, 1990), and herbicidal activities (Subramanian & Gerwick, 1989). Neonicotinoid insecticides, as nicotinic acetylcholine receptor inhibitors, have also attracted increasing attention because of their low toxicity, wide range of activities, and high potency (Shiokawa et al., 1986). It has been found that most biologically active nicotinic compounds contain the 3-aminomethylpyridine group (Yamamoto et al., 1994). Herein, we report the crystal structure of (I), Fig. 1, which was synthesized by introducing pyridine rings into a 1,2,3-triazolo[4,5-d]pyrimidine framework.
Several N—H···N hydrogen bonding contacts, together with C—H···N and C—H···π interactions, lead to the formation of supramolecular arrays in the ab plane, Table 1 and Fig. 2. In addition π—π stacking interactions stabilize the crystal structure, with the shortest centroid-centroid distance of 3.412 (1) Å occurring between centrosymmetrically related planes through the (N4–N6, C1, C4) rings, symmetry operation: 2-x, 1-y, 1-z.
