Räder neu erfunden : Die Reaktion von [M 3 (CO) 12 ] (M=Ru, Os) mit 4‐RC 6 H 4 SH ergibt die Produkte [{M(S‐4‐R‐C 6 H 4 ) 2 (CO) 2 } 8 ] (R=H; I ) oder [{M(S‐4‐R‐RC 6 H 4 ) 2 (CO) 2 } 6 ] (R=Me, i Pr; II ; siehe Bild). Die Oktamere I sind molekulare Räder aus verdrillt‐kantenverknüpften Oktaedern um ein zentrales planares M 8 ‐Achteck. Durch die selektive Bindung eines Cu + ‐ oder Ag + ‐Ions an [{Ru(S‐4‐ i Pr‐C 6 H 4 ) 2 (CO) 2 } 6 ] entsteht [M′{Ru(S(4‐ i Pr‐C 6 H 4 )) 2 (CO) 2 } 6 ] + ( III ).
