Two novel Zn(Ⅱ)-organic frameworks[(CH3)2NH2][Zn(BPT)]·0.5DMF(1)and[Zn2(HBPT)2(1,4-bis)](2)(H3BPT=biphenyl-3,4,5-tricarboxylic acid,1,4-bis=1,4-bis(1Himidazol-1-yl)butane)have been synthesized under solvothermal conditions,and characterized by IR spectroscopy,powder X-ray diffractions(PXRD)and single-crystal X-ray diffractions.Complex 1displays a rtl rutile 3,6-connected network with{4.62}2{42.610.83}topology,while with the 1,4-bis secondary ligand being introduced into the assembly,a different structure 2 has been obtained.Compound 2 forms a 2D layered framework through linking by both BPT and 1,4-bis ligands,which is further stacked via hydrogen-bonding interactions to a three-dimensional supramolecular architecture.Furthermore,thermal analyses(TGA)and photoluminescent properties of 1 and 2 are also investigated in detail.

Two novel Zn (II) -organic frameworks [(CH3) 2NH2] [Zn (BPT)] · 0.5DMF (1) and [Zn2 (HBPT) 3,4,5-tricarboxylic acid, 1,4-bis = 1,4-bis (1Himidazol-1-yl) butane has been synthesized under solvothermal conditions, and characterized by IR spectroscopy, and single-crystal X-ray diffractions. Complex 1 displays a rtl rutile 3,6-connected network with {4.62} 2 {42.610.83} topology, while with the 1,4-bis secondary ligand are introduced into the assembly, a different structure 2 has been obtained. Compound 2 forms a 2D layered framework through linking by both BPT and 1,4-bis ligands, which is further stacked via hydrogen-bonding interactions to a three-dimensional supramolecular architecture. Futurertherm, thermal analyzes (TGA) and photoluminescent properties of 1 and 2 are also investigated in detail.
