| Outline of Final Research Achievements |
2D coordination polymers consisting of MnIII Schiff-base complexes and dicarboxylic acids, [{Mn(salen)}4(L1)](PF6)2;(CH3OH)2 (C4; HL1 = adipid acid) and [{Mn(salen)}4(L2)](PF6)2;(CH3OH)4 (C4’; HL2 = E,E-1,3-butadiene-1,4-dicarboxylic acid), were synthesized by using a one-pot reaction. Slow relaxations of the magnetizations for both C4 and C4’ were observed, which originated from the 1D single-chain magnets (SCMs), because C4 and C4’ showed magnetic correlations. From analysis of the alternating current (AC) susceptibilities for C4 and C4’, although C4 behaved as an SCM with a single relaxation process, the distribution of relaxation times for C4’ was broad due to Jlinker. Moreover, the broad distribution of the relaxation times for C4’ narrowed upon applying a magnetic field and by heating. This is the first report showing a direct correlation between interchain interactions and slow magnetic relaxation for SCMs.
