Why doesn't chromium 2+ ion use all its d-orbitals to receive lone pairs from six waters in [Cr(H20)6)]3+?

I'm guessing it's because the ligand experiences too much electron repulsion or proton repulsion from the chromium to insert them close to the 3d-orbitals which are close to the metal nucleus. Is...
