Abstract
An easy synthesis of pyridinium fluorochromate (PFC), C5H5NH[CrO3F], was developed by reacting CrO3 with NH4HF2 in the presence of pyridine. The structure of PFC was determined by X-ray diffraction. The crystals are orthorhombic, space group Cmc21, with a = 8.360(3) Å, b = 7.312(4)Å, c = 12.160(5) Å, V= 743.4(6) Å, and Z = 4; R = 0.0347 for 409 reflections with I>2sI. The structure consists of discrete pyridinium, C5H5NH+, cations and fluorochromate, [CrO3F]-, anions with a crystallographic mirror plane passing through the chromium, one oxygen and a fluorine atom.
