Abstract
The title compound, C15H17N5O2, was synthesized as part of a series of benzoxadiazole analogs which were examined for fluorescent properties by Cu-catalysed azide–alkyne cycloaddition (CuAAC) of a 4-azidomethyl-benzoxadiazole substrate. The structure shows a nearly coplanar orientation of the hexanone keto group and the 1,2,3-triazole ring [dihedral angle = 4.3 (3)°], while the benzoxadiazole and triazole groups are much more severely inclined [dihedral angle = 70.87 (4)°]. In the crystal, weak C—H⋯N interactions connect translationally-related triazole rings, while another set of C—H⋯N interactions is formed between inversion-related benzoxadiazole units, forming a three-dimensional network. The crystal studied was a non-merohedral twin with refined value of the twin fraction of 0.2289 (16).

[PMID: 21837221 PMCID: PMC3151948 DOI: 10.1107/s1600536811019994] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2011] [Accepted: 05/26/2011] [Indexed: 12/02/2022]
Abstract
In the title compound, C19H15N3, the benzyl group is almost perpendicular to the triazole ring [dihedral angle = 80.64 (8)°], while the napthyl group makes an angle of 30.27 (12)° with the plane of the triazole ring. This conformation is different from the 1-benzyl-4-phenyl-1H-1,2,3-triazole analogue, which has the benzyl ring system at an angle of 87.94° and the phenyl group at an angle of 3.35° to the plane of the triazole ring.
