1-[1-(2,1,3-Benzoxadiazol-5-ylmeth-yl)-1H-1,2,3-triazol-4-yl]hexan-1-one.

ABSTRACT: The title compound, C(15)H(17)N(5)O(2), was synthesized as part of a series of benzoxadiazole analogs which were examined for fluorescent properties by Cu-catalysed azide-alkyne cyclo-addition (CuAAC) of a 4-azido-methyl-benzoxadiazole substrate. The structure shows a nearly coplanar orientation of the hexa-none 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 inter-actions connect translationally-related triazole rings, while another set of C-H?N inter-actions 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).

5-(1-Benzyl-1H-1,2,3-triazol-4-yl)-2,1,3-benzoxadiazole.

Project description:In the title compound, C(15)H(11)N(5)O, which was prepared as part of a study to identify fluoro-genic substrates for the Cu-catalysed azide-alkyne cyclo-addition (CuAAC) reaction, the benzoxa-diazole unit and the triazole ring are much more closely coplanar [dihedral angle = 10.92?(7)°] than either is to the benzyl group [dihedral angles = 69.13?(3)° and 78.20?(4)°, respectively]. The crystal structure features two different sets of weak inter-molecular C-H?N inter-actions between adjacent benzoxadiazole and triazole rings, forming a chain that propagates in the [-110] direction parallel to the ab plane.

5-(4-Hexyl-1H-1,2,3-triazol-1-yl)-2,1,3-benzoxadiazole.

Project description:The title compound, C(14)H(17)N(5)O, a 1,2,3-triazole derivative of benzoxadiazole (C(14)H(17)N(5)O), was synthesized via Cu-catal-ysed azide-alkyne cyclo-addition (CuAAC) from the corres-ponding n-octyne and 4-azido-benzoxadiazole. The benz-oxa-diazole and triazole rings show a roughly planar orientation [dihedral angle between the ring planes = 12.18?(5)°]. The alkane chain adopts a zigzag conformation, which deviates from the central triazole ring by 20.89?(6)°. These two torsion angles result in an overall twist to the structure, with a dihedral angle of 32.86?(7)° between the benzoxadiazole group and the hexyl chain. The crystal structure features C-H?N hydrogen bonds leading to chains propagating along [2-10] and offset parallel stacking inter-actions of the triazole and benzoxadiazole rings. The centroid of the extended ?-system formed by the benzoxadiazole and triazole rings (14 atoms total) was calculated; the centroid-centroid distance was 4.179?Å, interplanar separation was 3.243?Å, and the resulting offset was 2.636?Å.

Project description:The mol-ecule of the title compound, C(18)H(17)N(7)S, is non-planar, with a dihedral angle of 71.4?(4)° between the two triazole rings, and an angle of 15.5?(3)° between the two phenyl rings. An intra-molecular N-H?S hydrogen bond forms a five-membered ring.

Crystal structure of 1-{1-[2-(phenyl-selan-yl)phen-yl]-1H-1,2,3-triazol-4-yl}cyclo-hexan-1-ol.

Project description:Two independent mol-ecules, A and B, comprise the asymmetric unit of the title compound, C20H21N3OSe. While the benzene ring directly bound to the central triazole ring is inclined to the same extent in both mol-ecules [dihedral angles = 40.41 (12) (mol-ecule A) and 44.14 (12)° (B)], greater differences are apparent in the dihedral angles between the Se-bound rings, i.e. 74.28 (12) (mol-ecule A) and 89.91 (11)° (B). Close intra-molecular Se⋯N inter-actions of 2.9311 (18) (mol-ecule A) and 2.9482 (18) Å (B) are noted. In the crystal, supra-molecular chains along the a axis are formed via O-H⋯N hydrogen bonding. These are connected into layers via C-H⋯O and C-H⋯N inter-actions; these stack along (01-1) without directional inter-molecular inter-actions between them.

N-(1H-1,2,3-Benzotriazol-1-ylmeth-yl)phthalimide.

Project description:THE TITLE COMPOUND [SYSTEMATIC NAME: 2-(1H-1,2,3-benzotriazol-1-ylmeth-yl)isoindole-1,3-dione], C(15)H(10)N(4)O(2), was prepared by the reaction of 1H-benzotriazole and 2-bromo-methyl-isoindole-1,3-dione. The benzotriazole and isoindole units are almost planar and make a dihedral angle of 70.2?(1)° (mean planes include C and N atoms). A weak C-H?O intra-molecular hydrogen bond involving a carbonyl O atom as acceptor stabilizes the observed mol-ecular conformation.

Project description:In the title compound, C18H16N4OS, the six-membered heterocycle of the benzo-thia-zine fragment exhibits a screw-boat conformation.

In the crystal, mol-ecules are linked by C-H⋯N and C-H⋯O inter-actions, forming a three-dimensional network.

[1-(3-Chloro-phen-yl)-1H-1,2,3-triazol-4-yl]methanol hemihydrate.

Project description:The asymmetric unit of the title hydrate, C(9)H(8)ClN(3)O·0.5H(2)O, comprises two independent 1,2,3-triazole mol-ecules and a water mol-ecule of crystallization. The dihedral angles between the six- and five-membered rings in the 1,2,3-triazole mol-ecules are 12.71?(19) and 17.3?(2)°. The most significant different between them is found in the relative orientations of the terminal CH(2)OH groups with one being close to perpendicular to the five-membered ring [N-C-C-O torsion angle = 82.2?(5)°], while in the other mol-ecule, a notable deviation from a perpendicular disposition is found [torsion angle = -60.3?(5)°]. Supra-molecular chains feature in the crystal packing sustained by O-H?(O,N) inter-actions along the a-axis direction. The chains are connected via C-H?N inter-actions and the resultant layers stack along the b axis.

Crystal structure and Hirshfeld surface analysis of 1-[(1-butyl-1H-1,2,3-triazol-4-yl)meth-yl]-3-methyl-quinoxalin-2(1H)-one.

Project description:The title compound, C16H19N5O, is built up from a planar quinoxalinone ring system linked through a methyl-ene bridge to a 1,2,3-triazole ring, which in turn carries an n-butyl substituent. The triazole ring is inclined by 67.09 (4)° to the quinoxalinone ring plane. In the crystal, the mol-ecules form oblique stacks along the a-axis direction through inter-molecular C-HTrz⋯NTrz (Trz = triazole) hydrogen bonds, and offset π-stacking inter-actions between quinoxalinone rings [centroid-centroid distance = 3.9107 (9) Å] and π-π inter-actions, which are associated pairwise by inversion-related C-HDhydqn⋯π(ring) (Dhydqn = di-hydro-quinoxaline) inter-actions. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H⋯H (52.7%), H⋯N/N⋯H (18.9%) and H⋯C/C⋯H (17.0%) inter-actions.

In the crystal, mol-ecules are linked by C-H?N hydrogen bonds into tapes parallel to the b axis. The tapes are linked together by ?-? inter-actions between triazole rings [inter--centroid distance = 3.4945?(9)?Å].
