Abstract: | The Crystal Structures of (DDI)2Sb2F6O] and (DDI)2Sb3F7O2] (DDI = 1,3‐Diisopropyl‐4,5‐dimethylimidazolium) — a Contribution to the Hydrolysis of SbF3 1] The salts (DDI)2Sb2F6O] ( 2 ) and (DDI)2Sb3F7O2] ( 3 ), (DDI = 1,3‐diisopropyl‐4,5‐dimethylimidazolium) are obtained by hydrolysis of C11H20N2SbF3 ( 1 ). The anion Sb2F6O]2? consists of two SbF2 fragments linked by a symmetrical oxygen bridge and two unsymmetrical fluorine bridges to form a distored ψ‐octahedral coordination sphere at the antimony atoms. In Sb3F7O2]2?, two SbF2 units are linked by a symmetrical fluorine bridge, while the third antimony atom is connected with each SbF2 fragment by a symmetrical oxygen and an unsymmetrical fluorine bridge. The antimony atoms adopt the centres of strongly distored ψ‐polyhedra. |
