摘　　要：Polyoxometalate-based metal-organic polyhedra(MOPs)were of particular concern because of the various exquisite building blocks and the suitable constructional characteristics.To further understand the design and particularity of polyoxovanadate-based MOPs,(NH_(2)Me)_(8){[V_(6)O_(6)(OCH_(3))_(9)(C_(6)H_(5)PO_(3))]_(4)·(BPT)_(4)}·2DMF(HNU-74)and(NH_(2)Me)12{[V_(6)O_(6)(OCH_(3))_(9)(C_(6)H_(5)PO_(3))]4·(HBCBAIP)_(4)}(SO_(4))_(2)·MeOH·DMF(HNU-75)were constructed by a face-directed synthesis strategy.Both structures were assembled with four secondary building units as vertexes and four organic ligands served as faces.Different from HNU-74,HNU-75 showed a carboxyl group free during the coordination process,resulting in the pore channels being blocked and the free carboxyl group linking outwards,paving the way for the formation of the 3D structure.Due to the pore channels of HNU-74,the adsorption of I2 was studied and the adsorption capacity was 148 mg/g.
