XeF₄ : AX₄E₂ ;     BF₄^- : AX₄ ;     SF₄ : AX₄E ;     SiF₄ : AX₄

square planar: AX₄E₂

ClF₃ : AX₃E₂ ;     PF₃ : AX₃E ;     ClO₃^- :     AX₃E ;     NH₃ : AX₃E

T-shaped: AX₃E₂

H₂O: 4 electron groups around the central oxygen atom (2 neighboring atoms + 2 lone pairs)

ICl₂^-: 5 electron groups around the central iodine atom (2 neighboring atoms + 3 lone pairs) ⇒ AX₂E₃

SF₆ is octahedral (AX₆) ⇒ bond dipoles in PF₆ cancel each other ⇒ overall dipole moment of PF₆ = 0

SO₂ is bent (AX₂E) ⇒ bond dipoles do not cancel each other ⇒ overall dipole moment of SO₂ $\ne$ 0
