Abstract Three new mixed-ligand metal-organic frameworks based on 5,5′-(butane-1,4- diyl)-bis(oxy)-diisophthalic acid and transitional metal cations with the help of two ancillary bridging N-donor pyridyl and imidazole linkers, [Zn(L){sub 0.5}(4,4′-bpy)]·2(H{sub 2}O) (1), [M(L){sub 0.5}(bib)]·4(H{sub 2}O) (M = Zn (2), Co (3)), (4,4′-bpy=4,4′–bipyridine, bib=1,4-bis (1H-imidazol-1-yl)-butane), have been synthesized under solvothermal conditions. Their structures and properties were determined by single-crystal and powder X-ray diffraction analyses, IR spectra, elemental analyses and thermogravimetric analyses (TGA). Compounds 1–3 display a 3D 3-fold interpenetrated frameworks linked by the L{sup 4−} ligands, ancillary N-donor linkers and the free water molecules in the crystal lattice. Topological analysis reveals that 1–3 are a (4,4)-connected bbf topology net with the (6{sup 4}·8{sup 2})(6{sup 6}) topology. The effects of the L{sup 4−} anions, the N-donor ligands, and the metal ions on the structures of the coordination polymers have been discussed. Furthermore, luminescence properties and thermogravimetric properties of these compounds were investigated. - Graphical abstract: Three new compounds of MOFs have been prepared and characterized. The luminescence properties and thermogravimetric properties of compounds were investigated. Display Omitted.
