Mg 3 @C 20 + : an s-orbital electron spin system protected in carbon ring framework

Key Points

• The aim is to explore how increasing s-orbital character and using rigid ligands affect electron spin interactions.
• Experimental design focused on electron spin systems within a carbon ring framework.
• Use of rigid ligands to introduce zero nuclear spin and suppress coupling effects.
• Successful suppression of spin-orbit coupling and hyperfine coupling in the s-orbital character increase.
• Demonstrated stability of spin properties within the carbon framework.
