Which molecule contains the smallest $\mathrm{F}-\mathrm{S}-\mathrm{F}$ angle?

Six fluorine atoms are covalently joined to a Sulphur atom in the middle to form Sulphur hexafluoride, often known as ${\mathrm{SF}}_6$. According to the $\mathrm{VSEPR}$Theory, these six zones of electron density, which are represented by the single bonds between the Sulphur and fluorine atoms, would organize themselves in $3-\mathrm{D}$ space as distant from one another as feasible. The octahedron-like arrangement that optimizes the separation between these electron density zones. There will be two fluorine atoms in axial locations and four fluorine atoms in equatorial positions. The molecular geometry of Sulphur hexafluoride will be octahedral. The four equatorial linkages will be situated $90°$ degrees apart from one another. Similar to how the axial and equatorial linkages will be at a $90°$ degree angle from one another.
