pcl5 have a trigonal bipyramidal structure . 
if u can see the electronic configuration then it suggest us to use sp3d hybrid orbitals on phosphorous . each chlorine atom have singly occupied 3p orbitals . the p-cl bond formed by the overlapping of phosphorous sp3d hybrid orbitals with singly occupied chlorine 3p orbitals , each cl hold 3 loan pairs . 
hence in pcl5 the electron pair is 5 , so, the bond pair is also 5 . 
2- in pcl3 , the electron pair is 3 and bond pair is 3 and it has 1 loan pair electron it have sp3 hybridisation . 
so, this suggest the trigonal pyramidal shape . 
HOPE IT CLEARS ..
