☒N (what is checkY☒N ?)

Copper(II) carbonate or cupric carbonate is a chemical compound with formula CuCO
3
. At ambient temperatures, it is an ionic solid (a salt) consisting of copper(II) cations Cu2+
and carbonate anions CO2−
3
.

This compound is rarely encountered because it is difficult to prepare[2] and readily reacts with water moisture from the air. The terms "copper carbonate", "copper(II) carbonate", and "cupric carbonate" almost always refer (even in chemistry texts) to a basic copper carbonate (or copper(II) carbonate hydroxide), such as Cu
2
(OH)2CO
3
(which occurs naturally as the mineral malachite) or Cu
3
(OH)2(CO
3
)2 (azurite). For this reason, the qualifier neutral may be used instead of "basic" to refer specifically to CuCO
3
.
