Abstract	The synthesis and characterization of 3d/4f heterometallic clusters in intermediate oxidation states is one of the main research οbjectives in this field of chemistry. Such clusters often contain an unusually large number of unpaired electrons in the ground state and are of great interest from a magnetic behavior point of view, especially when they display single molecule magnetism properties (SMMs). In this work, we investigated the triad reaction system Mn/LnIII/Η3L, where LH3: 2-(β-naphthalideneamino)-2-hydroxymethyl-1-propanol), under aerobic conditions. From the above mentioned synthetic system we were able to isolate and fully characterize three closely related families, named: [MnIII6LnIII2], [MnIII6LnIII4], and [MnIII6LnIIII6]. The first group of octametallic heteronuclear complexes displays the general molecular formula: [MnIII6LnIII2O2 (OH) 2(HL) 6 (NO3)6 (H2O) 2]•6MeCN•0.5H2O (Ln: Gd(1), Tb(2), Dy(3), Er(4) and Y(5)), the second decametallic family displays general formula: [MnIII6LnIII4 (O)(OH) 7 (HL) 6 (OAc) 6 (MeO)(H2O) 3].3MeOH.(NO3) 2 (Ln: Gd(1), Tb(2), Dy(3), Ηο(4), Y(5)), while finally, the last family of dodecametallic clusters displays the general formula [MnIII6LnIII6 (OH) 7 (O2CPh) 11 (L) 3 (HL) 4 (NO3)(H2O) 3] .6.5MeCN.H2O, (Ln: Gd(1) and Dy(2)). All complexes are high nuclearity MnIII/LnIII species, with aesthetically beautiful structures and interesting magnetic properties.
