Dear shreya k,

[XeF5]- has 5 bond paris and two lone pairs & therefore it has a pentagonal planar structure !!

 

Hope this helped you immensely....

All the very Best & Good Luck to you ...

It is pentagonal planar but that’s because lone pair repulsion is greater than bond pair repulsion. So the two lone pairs occupy the apices of a pentagonal bipyramidal stucture. This places them further away from the other electron pairs then they would be if they were in the plane of five.
