Thanks AWK!

I just see, this is copper (II) but I need copper(I) 

[AWK]

Are you sure these compound are known and they are stable?

[sanya86]

I'm not sure for Cu(I). but for Ni I am.
I know that NiCl₂ + (NH₄)₂CO₃  NiCO₃ + 2H₄Cl
and in the presence of excess (NH₄)₂CO₃ ,  NiCO₃  [Ni(NH₃)₆]CO₃

But this link is to Copper(II) compound

[sanya86]

Sorry, my mistake. I don't know where to look for it... Thanks for *delete me*

[AWK]

Probably your compounds were not obtained yet.
May be the second one can be obtained by dissolution of pure NiCO₃ in liquid ammonia. In aqueous solution you will rather obtain a basic nickel carbonate instead.

Thanks AWK. I'll try it tomorrow.
