The molecules having square pyramidal geometry are

Core Logic

Let us check the steric details using VSEPR theory:

• BrF₅$\mathrm{BrF}_5$: Bromine has 7 valence electrons. It forms 5 single bonds with Fluorine and retains 1 lone pair. Steric number = 6 (sp³d²$sp^3d^2$), geometry is square pyramidal.
• XeOF₄$\mathrm{XeOF}_4$: Xenon has 8 valence electrons. It forms 1 double bond with Oxygen, 4 single bonds with Fluorine, and retains 1 lone pair. Steric number = 6 (sp³d²$sp^3d^2$), geometry is square pyramidal.
• SbF₅$\mathrm{SbF}_5$ & PCl₅$\mathrm{PCl}_5$: Central element has 5 valence electrons, forming 5 bonds with no lone pairs. Steric number = 5 (sp³d$sp^3d$), geometry is trigonal bipyramidal.

Pattern Recognition

Sees: Steric count 6 with 5 bonded segments + 1 lone pair arrow$\rightarrow$ always square pyramidal geometry.
