Abstract The Crystal Structures of (DDI) 2 [Sb 2 F 6 O] and (DDI) 2 [Sb 3 F 7 O 2 ] (DDI = 1,3‐Diisopropyl‐4,5‐dimethylimidazolium) — a Contribution to the Hydrolysis of SbF 3 [1] The salts (DDI) 2 [Sb 2 F 6 O] ( 2 ) and (DDI) 2 [Sb 3 F 7 O 2 ] ( 3 ), (DDI = 1,3‐diisopropyl‐4,5‐dimethylimidazolium) are obtained by hydrolysis of C 11 H 20 N 2 SbF 3 ( 1 ). The anion [Sb 2 F 6 O] 2− consists of two SbF 2 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 [Sb 3 F 7 O 2 ] 2− , two SbF 2 units are linked by a symmetrical fluorine bridge, while the third antimony atom is connected with each SbF 2 fragment by a symmetrical oxygen and an unsymmetrical fluorine bridge. The antimony atoms adopt the centres of strongly distored ψ ‐polyhedra.
