title: 4-(3,3-Dimethyl-perhydro-1,3-oxa-zolo[3,4-a]pyridin-1-yl)-2,8-bis-(tri-fluoro-meth-yl)quinoline.
abstract: An L-shaped conformation is found in the title mol-ecule, C(20)H(20)F(6)N(2)O, the C-C-C-C torsion angle linking the two fused-ring systems being -92.80 (19)°. The oxazole ring adopts an envelope conformation [the N atom lies 0.579 (2) Å out of the plane defined by the remaining atoms], and the piperidine ring has a chair conformation. Supra-molecular chains are found in the crystal structure that are sustained by C-H⋯π and π-π [3.6089 (10) Å] inter-actions.
