So juangodoyite is mineral with formula Na2Cu(CO3)2, i think it isn´t just mixed carbonate, because of its solubility in water so it should be most
likely complex Na2[ Cu(CO3)2 ]. I tried to synthetize it by dissolving Cu(OH)2 in hot Na2CO3 solution, color changed
to deep blue, than i let it crystallize (pictures). Even after adding NaOH in solution any copper hydroxide didn´t precipitate so i think this
experiment was successful.
