Chirality shock: Geneva chemists forge millennia-stable ‘mirror-proof’ drugs
Can you imagine a life-saving molecule whose “twin” is a deadly poison? As surprising as it may seem, this chemical reality is known as “chirality.” Like a right hand and a left hand, two molecules can have the same composition, but a different…

Ferrocene derivative breaks 18-electron rule with unique 20-electron structure and unusual redox chemistry
A new derivative of ferrocene has 20 valence electrons, challenging the longstanding rule that organometallic compounds can only have a maximum of 18. The researchers highlight that the ligand structure alters the redox properties of the complex,…
