Methyl 1-(2,6-difluoro-benz-yl)-1H-1,2,3-triazole-4-carboxyl-ate.

ABSTRACT: In the title compound, C(11)H(9)F(2)N(3)O(2), the triazole ring is planar, with an r.m.s. deviation of 0.0048 Å, and makes a dihedral angle of 77.3 (1)° with the benzene ring. In the crystal, weak inter-molecular C-H⋯O and C-H⋯N hydrogen bonds link the mol-ecules into chains along the b axis.

Methyl 1-methyl-1H-1,2,3-triazole-4-carboxyl-ate.

Project description:The title mol-ecule, C(5)H(7)N(3)O(2), has an almost planar conformation, with a maximum deviation of 0.043?(3)?Å, except for the methyl H atoms. In the crystal structure, inter-molecular C-H?O hydrogen bonds link the mol-ecules into layers parallel to the bc plane. Inter-molecular ?-? stacking inter-actions [centroid-centroid distances = 3.685?(2) and 3.697?(2)?Å] are observed between the parallel triazole rings.

Ethyl 5-methyl-1-(4-nitro-phen-yl)-1H-1,2,3-triazole-4-carboxyl-ate.

Project description:In the title compound, C(12)H(12)N(4)O(4), the 1,2,3-triazole ring and the nitro group form dihedral angles of 37.93?(5) and 8.97?(12)°, respectively, with the phenyl ring. The mol-ecular structure is stabilized by an intra-molecular C-H?O hydrogen bond, which generates an S(6) ring motif. In the crystal, mol-ecules are linked by C-H?N hydrogen bonds into layers lying parallel to (100). The crystal structure is further consolidated by ?-? [centroid-centroid distance = 3.6059?(6)?Å] inter-actions.

Ethyl 1-(6-chloro-3-pyridylmeth-yl)-5-methyl-1H-1,2,3-triazole-4-carboxyl-ate.

Project description:In the title compound, C(12)H(13)ClN(4)O(2), the triazole ring carries methyl and ethoxy-carbonyl groups, and is bound via a methyl-ene bridge to a chloro-pyridine unit. There is evidence for significant electron delocalization in the triazolyl system. Intra-molecular C-H⋯O and inter-molecular C-H⋯N hydrogen bonds stabilize the structure.

Ethyl 2-(2,6-difluoro-benz-yloxy)-4-(4,6-dimethoxy-pyrimidin-2-yl)quinoline-3-carboxyl-ate.

Project description:In the title compound, C(25)H(21)F(2)N(3)O(5), the pyrimidine and difluoro-benz-yloxy rings are twisted away from the central quinoline ring system, making dihedral angles of 54.6?(1) and 74.1?(1)°, respectively. A weak C-H?O inter-action links symmetry-related mol-ecules, forming a pseudo-dimer. ?-? inter-actions between the quinoline rings of symmetry-related mol-ecules [centroid-centroid distance = 3.5479?(10)?Å] link these dimers into chains parallel to [101]. Weak C-H?? inter-actions join adjacent chains, forming a two-dimensional layer parallel to (101).
