Although crystallization is the most important method for the separation of enantiomers of chiral molecules in the chemical industry, the chiral recognition involved in this process is poorly understood at the molecular level. We report on the initial steps in the formation of layered racemate crystals from a racemic mixture, as observed by STM at submolecular resolution. Grown on a copper single‐crystal...
Alfred Werners Originalproben bieten auch heute noch Überraschungen: [Co(en)2(NO2)2]Br, um 1900 von Werners Doktorandin Edith Humphrey synthetisiert, kristallisiert nicht wie bisher gedacht als Konglomerat, sondern bildet lamellare Zwillingskristalle aus beiden Enantiomeren. Zusammen mit ähnlichen Befunden von weiteren Proben aus der Werner‐Sammlung wirft dies ein neues Licht auf die These, dass Werner...
