Sd3 or you can also say d3s.
Now the question arise in your mind that why not sp3. This explain on the basis of hybridisation . As d obitals are lower in energy than p orbitals (because inner d orbital is use and it mix with s orbital not outer p orbital) , so as you know whenever orbital mixing take place, they always try to mix with lower energy orbitals.
Thats why hybridisation is sd3/d3s.
