Microporous metal–organic frameworks constructed by Cu(I)/Zn(II), Tpt and 1,4-benzenedicarboxylate

Two novel metal–organic frameworks, [Cu(tpt)(bdc)1/2]n · nH2O (1) and [Zn(tpt)(bdc)1/2I]n (2) (tpt = 2,4,6-tris(4-pyridyl)-1,3,5-triazine, H2bdc = 1,4-benzenedicarboxylic acid), have been prepared by hydrothermal reactions. In complex 1, Cu(I) center is in a trigonal coordination environment with bidentate tpt coordinating Cu(I) atoms to form 1D zigzag chains, and bdc ligand links the zigzag chains to form a 2D layered structure. In complex 2, Zn(II) center is in a trigonal–pyramidal environment with bidentate tpt coordinating Zn(II) atoms to form zigzag chains, and bdc links the zigzag chains to form metal–organic framework which contains interesting hexagonal nano-channels.

Two microporous metal–organic frameworks have been assembled by tpt and bdc. The frameworks consist of Cu(I)/Zn(II)-tpt zigzag chains and 1,4-benzenedicarboxylate bidentate bridge. The Zn(II) complex exhibits intriguing hexagonal nano-channels.Figure optionsDownload as PowerPoint slide
