Good day everyone, 

I aimed to synthesize schiff base complexe with CuCl2. 2H2O.

But I only have an aldhyde Ir spectrum from which its schiff base was made?!!! 

Why this is happened? 

The reaction was as follow :

I added cu metal unhydrous ethanolic sol. Dropwise to hot  ethanolic sol. of schiff base then reflex for about 3 hrs.

Interesting.

In principle the formation of Schiff bases is reversible.
So, if the copper forms a really strong complex with the amine  it could drag the equilibrium back and form the aldehyde.

If you had strictly anhydrous conditions (and anhydrous CuCl2), you might have more luck.

As OP is "Metal Complexes", a term beyond my exact understanding, I'll ask about some stuff used to control Dandruff in shampoos for such use.

One of such "compounds" which I do not understand is "Selenium Sulfide", used in 1% solution. My understanding is that this material does not exist as a compound, but is more comparable to an Amalgam. Yet, a ring structure seems to exist:
