Abstract

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.
