6-Isopropyl-3-phenyl-5-(p-tolyloxy)-3H-1,2,3-triazolo[4,5-d]pyrimidin-7(6H)-one: whole-molecule disorder
The title compound, C(20)H(19)N(5)O(2), exhibits whole-molecule disorder the refined ratios of the two components being 0.57 (2):0.43 (2). In the major component, the essentially planar [maximum deviation 0.033 (17) Å] fused pyrimidine and triazole ring system forms a dihedral angle of 10.5 (3)° wi...

| Sumario: | The title compound, C(20)H(19)N(5)O(2), exhibits whole-molecule disorder the refined ratios of the two components being 0.57 (2):0.43 (2). In the major component, the essentially planar [maximum deviation 0.033 (17) Å] fused pyrimidine and triazole ring system forms a dihedral angle of 10.5 (3)° with the phenyl ring, while in the minor component of disorder this angle is 27.5 (5)°. The crystal structure is stabilized by π–π stacking interactions between symmetry-related triazole and pyrimidine rings, with centroid–centroid distances of 3.594 (10) Å. |
