Rauf und runter : Die molekularen M 10 ‐Räder [M 10 (OMe) 20 (O 2 CR) 10 ] (M=Ga, R=Me; M=Fe, R=Ph) konnten in einer templatfreien Synthese durch Einfügen eines Diolatliganden in M 18 ‐Räder überführt werden (siehe Kalottenmodell von [Ga 18 (pd) 12 (pdH) 12 (O 2 CMe) 6 (NO 3 ) 6 ] 6+ ; Ga gelb, O rot, N blau, C grau; pdH 2 =1,3‐Propandiol). Erstaunlicherweise werden beide M 18 ‐Räder beim Lösen in MeOH wieder in die M 10 ‐Räder umgewandelt.
