A novel enneanuclear manganese complex, [Mn9O4(Mesao)6(MeO)3(O2CMe)3(OH)(MeOH)2]·2.5DMF [1; Me-saoH2 = 2-hydroxyphenylethanone oxime], was synthesized. The structure of 1 contains an unusual [Mn9O4] core with an unprecedented defective “supertetrahedron” topology based on two parallel, onset stacked 9-MC-3 and 15-MC-6 metallacrown subunits. Magnetic studies indicate that 1 behaves as a single-molecule magnet.
