摘要

A highly connected metal-organic framework (MOF), namely, [Co-5(mu(3)-OH)(2)(iapt)(4)(4,4'-bipy)(0.5)(H2O)center dot CH3CN center dot 3H(2)O] (1) (H(2)iapt = 5-aminoisophthalic acid and 4,4'-bipy = 4,4'-bipyridine), is reported. 1 shows a complicated pentanodal 4,4,4,4,13-c 3D net with (4(3))(4(3))(4(3)) (4(3))(4(20).5(14).6(23).7(8).8(13)) topology based on an uncommon Co-5 cluster. The magnetic analysis reveals antiferromagnetic interactions in 1, and both the local spin-orbit coupling of octahedral Co(II) ions and the antiferromagnetic interactions are the primary factors in the magnetic behaviour.
