“…Excitation of the microcrystalline sample of (2), also at 260 nm, leads to the generation of similar fluorescence emissions, with the maximum emissions also located at 417 and 470 nm, indicating that the auxiliary bimb ligand has almost no influence on the emission mechanism. Thus, the fluorescence emission of (2) may be assigned to an intraligand -* transition of the bimb and iip 2À ligands (Ge et al, 2015).…”

Two new coordination polymers (CPs) formed from 5-iodobenzene-1,3-dicarboxylic acid (H2iip) in the presence of the flexible 1,4-bis(1H-imidazol-1-yl)butane (bimb) auxiliary ligand, namely poly[[μ2-1,4-bis(1H-imidazol-1-yl)butane-κ(2)N(3):N(3')](μ3-5-iodobenzene-1,3-dicarboxylato-κ(4)O(1),O(1'):O(3):O(3'))cobalt(II)], [Co(C8H3IO4)(C10H14N4)]n or [Co(iip)(bimb)]n, (1), and poly[[[μ2-1,4-bis(1H-imidazol-1-yl)butane-κ(2)N(3):N(3')](μ2-5-iodobenzene-1,3-dicarboxylato-κ(2)O(1):O(3))zinc(II)] trihydrate], {[Zn(C8H3IO4)(C10H14N4)]·3H2O}n or {[Zn(iip)(bimb)]·3H2O}n, (2), were synthesized and characterized by FT-IR spectroscopy, thermogravimetric analysis (TGA), solid-state UV-Vis spectroscopy, single-crystal X-ray diffraction analysis and powder X-ray diffraction analysis (PXRD). The iip(2-) ligand in (1) adopts the (κ(1),κ(1)-μ2)(κ(1), κ(1)-μ1)-μ3 coordination mode, linking adjacent secondary building units into a ladder-like chain. These chains are further connected by the flexible bimb ligand in a trans-trans-trans conformation. As a result, a twofold three-dimensional interpenetrating α-Po network is formed. Complex (2) exhibits a two-dimensional (4,4) topological network architecture in which the iip(2-) ligand shows the (κ(1))(κ(1))-μ2 coordination mode. The solid-state UV-Vis spectra of (1) and (2) were investigated, together with the fluorescence properties of (2) in the solid state.

“…Generally, the 2 self-assembly of MOFs is dominated by various factors such as organic ligand, metal ions, anions, reaction solvent, temperature, pH value, and so on. Then it is so important to select the organic ligand in the construction of MOFs [15][16][17]. For the past few years, using flexible ligands to create MOFs is a common tactics, especially the study of tetrakis(imidazol-1-ylmethyl)methane ligand has been a lot.…”

Three novel 3D metal-organic frameworks, {[Zn2(L)(BDC)2]•H2O}n (1), {[Cd2(L)2(BDC)]•(BDC)•7.7(H2O)}n (2), and {[Co(L)(H2O)2]•(BDC)•5(H2O)}n (3)(L = tetrakis(imidazol-1-ylmethyl)methane, H2BDC = 1,4-benzenedicarboxylic acid), have been successfully synthesized by self-assembly of transition-metal salts with a flexible N-containing ligand and 1,4-dicarboxybenzene ligand. Complexes 1-3 have 3D structures with various topologies. In complex 1, the L connects Zn(II) atoms to form 2D layers, which are linked by two kinds of 1D [Zn(BDC)]n chains to generate a 4-connected three-dimensional structure with (6•8 5)(6 4 •8 2)(8 6) topology. In complex 2, Cd(II) atoms are coordinated by L to furnish a 2D layer, and the adjacent layers are linked by BDC ligands as bridging ligands to general a new (4,5)-connected three-dimensional network with a point symbol of (4 4 •6 2)(4 4 •6 6). In Complex 3, the L ligands act as 4-connected linkers connecting Co(II) ions to display a 4-connected three-dimensional structure with 4•6 5 topological net directly. In addition, the solid-state fluorescence, infrared spectra, magnetic property and thermal stability of these complexes have also been investigated.
