Abstract
: Difluorochloronium(III) compounds were synthesized from the reaction of metal powders (Ru, Os, Ir, Au), metal fluor-ides (NbF 5 , SbF 3 , BiF 5 ) or a metal chloride (TaCl 5 ) with excess liquid chlorine trifluoride. The compounds ClF 2 [AuF 4 ], ClF 2 [ M F 6 ] ( M = Nb, Ta, Ru, Os, Ir, Sb, Bi) and ClF 2 [Ta 2 F 11 ] were obtained in crystalline form and their crystal structures were determined by single-crystal X-ray diffraction. The ClF 2+ cations in the investigated compounds are bent, containing two strong, short, mainly covalent Cl–F bonds and two sterically active, free valence electron pairs in a pseudo-tetrahedral arrangement. The
