The compound has crystallographic mirror symmetry with both the cation and the tetrahedral anion located across a mirror plane. The cation and anion are linked by a C—H O hydrogen bond.enInternational Union of CrystallographySingle-crystal X-ray studyT = 293 KR factor = 0.033wR factor = 0.083Data-to-parameter ratio = 15.1Mean (C–C) = 0.003 A°Article
