摘要

A novel uninodal 5-connected metal-organic framework (MOF), [Cd2L2(4,4'-bipy)(3/2)(H2O)(2)](n) (H2L = m-thioacetatebenzoic acid and 4,4'-bipy=4,4'-bipyridine), was prepared under hydrothermal condition It features an unusual brick-wall shape layer by 4,4'-bipy, which consists of right- and left-handed helical chains arrayed alternatively and finally expands by L2- to a rare 5-connected nov (4(4) 6(6)) topology network.
