WebIn crystalline materials chirality may originate from the special manner in which achiral modules are stacked together. This is for instance the case for monocrystalline chiral materials with a crystal point lattice that is intrinsically chiral (22 out of the 230 crystallographic point groups, arranged in 11 enantiomeric pairs). WebOne of the most interesting types of isomer is mirror-image stereoisomers, a non-superimposable set of two molecules that are mirror images of one another. The existence of these molecules is determined by concept known as chirality.
