Using VSEPR theory, the molecular structure of ${\mathrm{IF}}_5$ is best described as:

Because of the octahedral nature of the electronic structure of IF 5, the core atom, I, hybridises as ${\mathrm{sp}}^3{\mathrm{d}}^2$.

Five bonds and one lone pair are present in the centre atom of I, resulting in the molecular geometry for ${\mathrm{IF}}_5$.
