title: Crystal structure of 2-{[(naphthalen-1-yl)oxy]meth-yl}-5-(2,4,5-tri-fluoro-phen-yl)-1,3,4-oxa-diazole.
abstract: In the title compound C19H11F3N2O2, the oxa-diazole ring and the naphthalene ring system are approximately planar (r.m.s. deviations of 0.001 and 0.020 Å, respectively) and the oxa-diazole ring makes dihedral angles of 13.11 (1) and 7.59 (1)° with the naphthalene ring system and the tri-fluoro-phenyl ring, respectively. In the crystal, C-H⋯N hydrogen bonds link mol-ecules into chains along the a-axis direction, while C-H⋯F contacts form additional chains along the ac diagonal. These contacts generate sheets of mol-ecules approximately parallel to the (011) plane.
