WebApr 13, 2024 · Like molecules, solid crystals can exhibit mirror symmetry: the left and right forms are enantiomorphs. Enantiomorphism can occur even when the constituent molecules or ions are not chiral because they can pack together in a chiral pattern. Common quartz is a good example of a crystalline material with left and right enantiomorphs.
