A (3, 4, 10)-connected 3D sandwich-type metal-organic framework with trinuclear zinc(II) cluster and two kinds of discrete zinc(II) ions

A new 3D sandwich-type MOF named [Zn3(bptc)1.5(H2O)4]·C2H5OH·2H2O (1) (H4bptc = biphenyl-2,5,2',5'-tetracarboxylic acid) was obtained by solvothermal reaction, which represents a rare trinodal (3, 4, 10)-connected topology network. Moreover, the thermal stability, UV–vis absorption spectra and photoluminescent properties of 1 have been investigated as well.

A novel 3D zinc coordination complex was synthesized through solvothermal reaction between zinc salt and H4bptc. The complex 1 exhibits a rare (3, 4, 10)-connected topology network. In addition, the thermal stability, UV-vis absorption spectra and photoluminescent properties of 1 have been investigated.Figure optionsDownload as PowerPoint slideHighlights
