why pf5 exists but ph5 donot exists

PF5 exists but PH5 does not because of the following reasons -
H is smaller in size than F
PH5 is formed by the overlap of d orbitals with Sp3d hybridisation.
F is more electronegative so Sp3d hybridisation is possible but H has lesser electronegativity and can not form sp3d hybridization and PH5 cannot be formed.
