SF₄ is iso-structural with:

• A) BrF₄^-
• B) CH₄
• C) IF₄⁺
• D) XeF₄
• E) XeO₂F₂

SF₄ has:

• 5 electron pairs around sulfur
• 4 bond pairs and 1 lone pair
• Trigonal bipyramidal electron geometry
• Seesaw molecular shape

Now compare:

• BrF₄^- → Square planar
• CH₄ → Tetrahedral
• IF₄⁺ → Seesaw
• XeF₄ → Square planar
• XeO₂F₂ → Seesaw

Therefore IF₄⁺ and XeO₂F₂ have the same geometry as SF₄.
