Abstract
Сrystals of the previously unknown polymorph of potassium tetrafluoroantimonate(III) (β-KSbF4) are synthesized and their crystal structure is determined (orthorhombic crystal system: a = 8.1631(5) Å, b = 7.8563(5) Å, c = 6.5396(4) Å, V = 419.40(5) Å3, Z = 4, dcalc = 3.751 g/cm3, F(000) = 424, space group Pmn21). The main structural units of β-KSbF4 within the first coordination sphere are dimer complex [Sb2F8]2– anions formed of trigonal SbF4E and tetragonal SbF5E bipyramids with a common vertex. The previously described α-KSbF4 polymorph consists of tetrameric [Sb4F16]4– complexes formed of SbF5E bipyramids.
