1-{1-[2,8-Bis(trifluoro­meth­yl)-4-quin­olyl]-5-methyl-1H-1,2,3-triazol-4-yl}ethanone

There are two independent mol­ecules in the asymmetric unit of the title compound, C(16)H(10)F(6)N(4)O. The triazole ring is not coplanar with the quinoline ring system; the dihedral angle between the two planes being 74.47 (12) and 63.97 (13)° in the two mol­ecules. The crystal structure is charact...

Sumario:There are two independent mol­ecules in the asymmetric unit of the title compound, C(16)H(10)F(6)N(4)O. The triazole ring is not coplanar with the quinoline ring system; the dihedral angle between the two planes being 74.47 (12) and 63.97 (13)° in the two mol­ecules. The crystal structure is characterized by inter­molecular C—H⋯F, C—H⋯N and C—H⋯O hydrogen bonding. Weak intra­molecular C—H⋯F inter­actions are observed. Disorder is observed in two F atoms of one of the trifluoro­methyl groups of one independent mol­ecule [occupancy ratios 0.77 (3):0.23 (3) and 0.77 (4):0.23 (4)] and in all three F atoms of one of the trifluoro­methyl groups of the second independent mol­ecule [occupancy ratios 0.520 (14):0.480 (14), 0.615 (17):0.385 (17) and 0.783 (11):0.217 (11)]. The O atom is also disordered over two positions with occupancies of 0.60 (13) and 0.40 (13) in the first mol­ecule.
