摘要：

Two dysprosium complexes, [Dy-2(OAc)(6)H2O](n) (1) and {[DyL(H2O)(4)]ClO4 center dot H2O}(n) (2) (L=2,2' -dithiobis (3-pyridinecarboxylic acid)), were synthesized and structurally and magnetically characterized. Complex 1 is a 1D dysprosium chain, in which the dysprosium ions are bridged by OAc- anions, exhibiting slow magnetic relaxation behavior with an energy barrier of 2 K. Complex 2 is a 2D dysprosium network, in which the carboxylato-bridged dysprosium chains are linked by disulfide bonds, showing ferromagnetic interaction and slow magnetic relaxation.
