In which one of the following species the central atom has the type of hybridisation which is not the same as that present in the other three

In SbCl52−,Sb is sp3d2 hybridised, and rest are sp3dSF4: H=1/2[7+4−0+0]=5(sp3d)l−3: H=1/2[7+2−0+1]=5(sp3d)(SbCl5)2−: H=1/2[5+5−0+2]=6(sp3d2)PCl5: H=1/2[5+5−0+0]=5(sp3d)Where H=no. of hybrid orbitals
