this mean chemistry is true!!!! the only in which crystal can arrange is in  14 braviss lattice !!!except that u cant find any other different crystal type!!!! whether the compound is present on mars or venus based on that temperature , pressure and formation of crystal , the phase of the crystal may change!!!!based on change in phase may give rise to different chemical properties!!!!!
