Abstract
The crystal structure of L-leucinium tetrafluoroantimonate(III) of the composition (C6H14NO2)SbF4 (orthorhombic symmetry: a = 6.1459(6) Å, b = 14.994(1) Å, c = 24.789(2) Å, Z = 8, P212121 space group) synthesized for the first time is determined. The (C6H14NO2)SbF4 structure represents a new structure type of tetrafluoroantimonate(III). It is formed by (C6H14NO2)+ cations and chain complex [Sb2F8] anions composed of Sb2F8 dimers linked into chains by bridging F atoms. The Sb2F8 dimers consist of SbF3 and SbF5 groups bound by bridging fluoride atoms of the SbF5 group. Chains in the structure are linked by N-H…F, N-H…O, and O-H…F hydrogen bonds into a three-dimensional framework.
