Thecarbonate chlorides aredouble salts containing bothcarbonate andchlorideanions. Quite a few minerals are known. Several artificial compounds have been made. Some complexes have both carbonate and chlorideligands. They are part of the family of halocarbonates. In turn these halocarbonates are a part ofmixed anion materials.
The carbonate chlorides do not have a bond from chlorine to carbon, however "chlorocarbonate" has also been used to refer to thechloroformates which contain the group ClC(O)O-.
Scapolite is produced in nature bymetasomatism, where hot high pressure water solutions of carbon dioxide and sodium chloride modifyplagioclase.[1]
Chloroartinite is found inSorel cements exposed to air.[2]
In 2016 27 chloride containing carbonate minerals were known.[3]

The "lanthaballs" arelanthanoid atom clusters held together by carbonate and otherligands. They can form chlorides. Examples are [La13(ccnm)6(CO3)14(H2O)6(phen)18] Cl3(CO3)·25H2O where ccnm is carbamoylcyanonitrosomethanide and phen is 1,10-phenanthroline.Praseodymium (Pr) orcerium (Ce) can substitute forlanthanum (La).[28] Otherlanthanide cluster compounds include :(H3O)6[Dy76O10(OH)138(OAc)20(L)44(H2O)34]•2CO3•4Cl2•L•2OAc (nicknamed Dy76) and (H3O)6[Dy48O6(OH)84(OAc)4(L)15(hmp)18(H2O)20]•CO3•14Cl•2H2O (termed Dy48-T) with OAc=acetate, and L=3-furancarboxylate and Hhmp=2,2-bis(hydroxymethyl)propionic acid.[29]
Platinum can form complexes with carbonate and chloride ligands, in addition to anamino acid. Examples include the platinum compound [Pt(gluH)Cl(CO3)]2.2H2O gluH=glutamic acid, and Na[Pt(gln)Cl2(CO3)].H2O gln=glutamine.[30]Rhodium complexes include Rh2(bipy)2(CO3)2Cl (bipy=bipyridine)[31]
