摘要
The thermal behavior of three Mn-12 single molecule magnets [Mn12O12(O2CC6H5)(16)(H2O)(4)].CH2Cl2 C6H5CO2H (1), [Mn12O12(O2C'Bu)(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 degreesC 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)(10)L-4] (L = H2O, HO2CR) complexes as characterized by single crystal X-ray diffraction when R = 'Bu.
