in hydrated copper ii sulfate complex, is (so4)2-ionically bonded to cu2+?

A passage from George facer says : when hydrated copper ii sulfate is heated it turns white soon as it loses its water ligands. as there are now no ligands, there is no splitting and so it does not absorb visible light. Therefore anhydrous copper II sulfate is white.

This implies that (so4) 2 - must not have been a ligand & so (so4 )2 - must have been ionically bonded to cu2+.

Yes, the lattice contains two types of ion:

[Cu(H2O)6]2+ ions and SO42- ions
