Geometry of ${\text{SF}}_4$ is:

In sulfur tetrafluoride (${\text{SF}}_4$), the central sulfur atom has 6 valence electrons. It forms 4 single bonds with fluorine atoms, leaving 1 lone pair of electrons.
According to VSEPR theory, the total steric number is:

$$\text{Steric Number}=4\text{ bond pairs}+1\text{ lone pair}=5$$

This corresponds to ${\text{sp}}^3\text{d}$ hybridization with a trigonal bipyramidal electron geometry. To minimize lone pair-bond pair repulsions, the lone pair occupies an equatorial position. The resulting molecular geometry is a distorted tetrahedral structure commonly known as a see-saw geometry.
