| Popis: | The reactions of Zn(NO3)2·6H2O with mixed ligands of 5-amino-tetrazole (Hatz) and l,2,4,5-benzenetetracarboxylic acid (H4btec) under hydro(solvo)thermal conditions, gave two three-dimensional (3D) porous metal-organic frameworks (MOFs) of {[Zn3(atz)2(btec)(DMF)2]·DMF·2H2O}n (1) and [Zn2(Hprz)(atz)(btec)(H2O)]n (2) in the absence and presence of piperazine (prz), respectively. 1 and 2 were characterized by infrared spectra (IR), elemental analyses (EA) and single-crystal/powder X-ray diffraction. In 1, the adjacent 1D [Zn3(btec)]n2n+ chains are linked together by atz− ligands to form a 3D porous MOF with 1D tetragonal channels filled with coordinated and guest DMF, and lattice water molecules. In 2, the adjacent 2D [Zn2(btec)]n wavelike sheets are pillared through atz− ligands to generate a 3D layered-pillared porous MOF with 1D open channels, which are occupied by coordinated Hprz+ cations and coordinated water molecules. Additionally, thermal stabilities and photoluminescent properties of both compounds in the solid-state at room temperature have been investigated and discussed in detail. |
