三种新颖的N,N′-双(2-羟基-3-甲氧基苯亚甲基)-1,3-丙二胺二聚镧系配合物,即[{H2 L}Sm(NO3)3]2·H2O(1),[{H2 L}Gd(NO3)3]4·CH 3OH(2),[{H2 L}Lu(NO3)3]4·H2O(3)(H_2L =N,N′-双(2-羟基-3-甲氧基苯亚甲基)-1,3-丙二胺)和三个新的N,N′-双(2-羟基-3-甲氧基苯亚甲基)-1,3-丙二胺(2-羟基-3-甲氧基亚苄基)-1,3-丙二胺3d-Gd异双核配合物,即[{LCo}(CH 3COO)(CH 3COOH)Gd(NO 3)2](4),合成并分离了[{LNi(MeOH)2}Gd(NO3)3]·2 MeOH(5)和[{(L)Zn(HNO 3)}Gd(NO3)3]·NO3·H3 O·MeOH(6)。X射线晶体学分析表明,配合物1-3是同构的,具有独特的二聚体拓扑结构。配合物4-6是离散的3d-4f双核。系统地研究了配合物2和4-6的磁性。配合物4和5是铁磁性的,而2和6是反铁磁性的。
Three novel N,N′-bis(2-hydroxy-3-methoxybenzylidene)-1,3-diaminopropane dimeric lanthanide complexes, namely, [{H2L}Sm(NO3)3]2·H2O (1), [{H2L}Gd(NO3)3]4·CH3OH (2), [{H2L}Lu(NO3)3]4·H2O (3) (H2L=N,N′-bis(2-hydroxy-3-methoxybenzylidene)-1,3-diaminopropane) and three new N,N′-bis(2-hydroxy-3-methoxybenzylidene)-1,3-diaminopropane 3d-Gd heterodinuclear complexes, namely, [{LCo}(CH3COO)(CH3COOH)Gd(NO3)2] (4), [{LNi(MeOH)2}Gd(NO3)3]·2MeOH (5) and [{(L)Zn(HNO3)}Gd(NO3)3]·NO3·H3O·MeOH (6) have been synthesized and isolated. X-ray crystallographical analysis reveals that complexes 1–3 are isomorphic with unique dimeric topology. Complexes 4–6 are of discrete 3d–4f dinuclear cores. Magnetic properties of complexes 2 and 4–6 are systematically investigated. Complexes 4 and 5 are ferromagnetic, while 2 and 6 are antiferromagnetic.
