Azurit hat die chemische Formel Cu3(CO3)2(OH)2, wobei Kupfer(II)-Kationen sowohl an Carbonat- als auch an Hydroxidanionen gebunden sind. Es ist eines von zwei relativ häufigen basischen Kupfer(II)-Carbonat-Mineralien, das andere ist der leuchtend grüne Malachit. Aurichalcit hingegen ist ein seltenes basisches Carbonatmineral, das Kupfer und Zink enthält. Einfaches Kupfercarbonat (CuCO3) kommt in der Natur nicht vor, da das Cu2+-Ion eine starke Affinität zum Hydroxidanion HO− hat.
