are these complex ions the same??

is Cu(OH)2 the same as [Cu(OH)2(H2O)4]?? (from the addition of a small amount of ammonia^) My text book and cgp guides give a different product so i’m not sure which one is right :/

I think it's the same. The latter is just the complex in water (with H2O ligands), but essentially the formula is Cu(OH)2

Cu(OH)2 is a simplified version. For most exam boards if they ask you for the equation for formation of the precipitate you can use this formula; in reality though the four waters from the original complex ion are still attached.
