Controlling Crystal Handedness in CsCuCl₃ (IMAGE)
Caption
Adding organic solvents to the crystallization solution allowed the chiral inorganic compound cesium copper chloride (CsCuCl₃) to form single-handed (enantiopure) crystals. Among the water-miscible organic solvents tested, ethylene glycol and 1-pentanol were particularly effective, leading to the formation of left- and right-handed crystals. When achiral crystal Cs₃Cu₃Cl₈(OH) was used as a seed, homochiral CsCuCl₃ crystals grew on its surface, demonstrating that chiral crystals can be produced even with an achiral template.
