?Organic minerals? means naturally occurring crystalline organic compounds including metal salts of formic, acetic, citric, mellitic and oxalic acids. The primary tool to disclose their crystal structure and their mutual relationship with each other and with synthetic analogues and also to understand their physicochemical properties is X-ray diffraction. The structure of several synthetic organic minerals was solved well before the discovery of their natural counterpart. On the other hand, complete crystal structure determination of early discovered organic minerals had to await the advent of combined synthetic and advanced X-ray diffraction methods. We review here the crystallography of organic minerals showing the importance of structural studies on their synthetic analogues. This will be highlighted by the cases of synthetic novgorodovaite, Ca2(C2O4)Cl2·2H2O, and its heptahydrate analogue, Ca2(C2O4)Cl2·7H2O, and the isotypic to each other stepanovite, NaMg[Fe(C2O4)3]·9H2O, and zhemchuzhnikovite, NaMg[AlxFe1-x(C2O4)3]·9H2O.
