Abstract:	The thermal behavior of three Mn₁₂ single molecule magnets [Mn₁₂O₁₂(O₂CC₆H₅)₁₆(H₂O)₄]·CH₂Cl₂·C₆H₅CO₂H (1), [Mn₁₂O₁₂(O₂C^tBu)₁₆(H₂O)₄] (2) and [Mn₁₂O₁₂(O₂CCHCl₂)₁₆(H₂O)₄] (3) is reported. Aromatic ligands allow the complex 1 to be stable up to 300 °C whereas alkyl groups decrease drastically the domain of thermal stability for the complexes 2 and 3. Moreover, the thermal decarboxylation of complexes 2 and 3 generates [Mn₆O₂(O₂CR)₁₀L₄] (L=H₂O, HO₂CR) complexes as characterized by single crystal X-ray diffraction when R=^tBu.
