| 英文摘要 | the reaction of mn(oac)(2)center dot 4h(2)o and ln(no3)(3)center dot 6h(2)o with n-(2-aminopropyl)-2-hydroxybenzamide and salicylic aldehyde in methanol/methylene dichloride produces yellow crystals of ln(2)mn(c7h5o2)(8) (ln = gd (1), tb (2), dy (3), ho (4) and er (5)), in the presence of triethylamine. three metal ions are connected by six mu(2)-phenolate oxygen atoms of six salicylic aldehyde ligands, resulting in perfect linear [ln(iii)-mn-ii-ln(iii)] structures. magnetic studies of these complexes have been performed and ac susceptibility measurements show the presence of a temperature-dependent out-of-phase ac signal for complexes 2 and 3 indicating single-molecule magnet (smm) behavior. the (dy2mnii)-mn-iii compound shows double relaxation pathways which may originate from the single ion behavior of individual dy-iii ions and the weak coupling between dy-iii and mn-ii ions, respectively. the u-eff of 92.4(2) k is a relatively high value among 3d-4f smms. moreover, complexes 2 and 3 represent the first linear mn-ln smms containing only divalent manganese ions as far as we know. the result suggests the positive effects of magnetic coupling to enhance their smm behavior, presenting a promising strategy for constructing efficient heterometallic smms. |
