通过扩链剂1，2-二(4-吡啶)乙烯(BPE)和三脚架Tecton 5-硝基-1，2，3-苯三甲酸的组合，合成了两个同构的金属有机骨架：{[M3(Nbtb)2(Bpe)3(H2O)2]·2H2O}n(M=Co(1)，Ni(2))。单晶X射线衍射研究表明，化合物1和2是(4，5)相连的(42·67·8)(42·67·8)(·82)(42·)拓扑结构。1的磁性表现为金属中心之间的弱反铁磁相互作用。
Two isomorphic metal–organic frameworks, {[M3(nbtb)2(bpe)3(H2O)2] · 2H2O} n (M = Co for (1) and Ni for (2)), have been synthesized by the combination of an extended linker 1,2-bi(4-pyridyl)ethene(bpe) and tripodal tecton 5-nitro-1,2,3-benzenetricarboxylic acid. Single-crystal X-ray diffraction studies indicate that 1 and 2 are (4, 5)-connected motifs containing (42 · 67 · 8) (42 · 67 · 8) (64 · 82) (42 · 64) topologies. The magnetic behavior of 1 exhibits weak antiferromagnetic interaction between metal centers.
