Description A novel oxo-bridged, carboxylate free 'ferric wheel' was isolated with the molecular formula [Fe-8(III)(mu-O)(4)(L2-)(8)] (1). Magnetic susceptibility measurements suggest that the Fe(III) ions are coupled anti-ferromagnetically and magnetic data modelling yields J(1) = -26.4 cm(-1), J(2) = -170 cm(-1) which are rationalized by DFT calculation. The exchange value for 1 of -170 cm(-1) (Fe-O(oxo)-Fe) is the largest exchange value known compared to any homometallic or heterometallic wheel reported to date.
