“…The 5-hip ligand appears in a number of MOFs, ,− coordination polymers, − metal–organic polyhedra, and supramolecular species . There are a number of homoleptic 5-hip MOFs, but most contain a secondary ligand. − The hydroxyl group of 5-hip also allows for alkylation or phenylation to occur at that site to add additional coordinating or chelating groups to increase the range of structures possible. − There are relatively few 5-hip MOFs where both carboxylates and hydroxyl groups coordinate to build a 3-D network, ,,,,, and the series of compounds presented here substantially expands the number of homoleptic 5-hip MOFs.…”

Three new metal-organic frameworks (MOFs) are formed from the reaction of zinc with 5-hydroxyisophthalic acid (H 3 -5-hip) with a range of additives in dimethylformamide (DMF). The additives include water, pyridine, and [Me n NH 4−n ]Cl (n = 0−4) and, through hydrogen bonding, have a marked effect on the formation and phase of any resultant MOF, often in a narrow range of sub-stoichiometric concentrations. The three MOFs, [Me 2 NH 2 ][Zn 2 (5-hip)(H-5-hip)(H 2 O)].3.25DMF (1), α-[Me 2 NH 2 ] 2 [Zn 2 (5-hip) 2 ]·2DMF (2) and [Me 2 NH 2 ][Me 4 N] 2 [Zn 4 (5-hip) 2 (H-5-hip 2.5 )]·3DMF (3) have solvent-accessible pores and the flexibility of the MOFs allows relaxation from a porous state to minimise the void space on desolvation. Topological analysis of the frameworks reveals two previously unrecorded MOF topologies. Compounds 2 and 3 are fluorescent while this property is absent in compound 1. We also present a revised structure for the closely-related β-[Me 2 NH 2 ] 2 [Zn 2 (5-hip) 2 ]·2DMF (4).

“…Organic-inorganic coordination polymers, especially those with d 10 metal centers, have been found to exhibit excellent luminescence properties and posses great potential applications as fluorescent-emitting materials [23][24][25][26][27][28]. Fluorescent properties of compounds 2, 3, and H 2 pip ligand were investigated in the solid state at room temperature and the emission spectra are depicted in Fig.…”

“…The luminescence of these two compounds should be ascribed as the p*-p transitions and metal-to-ligand charge transfer (MLCT) [29]. Incorporation of metal center effectively increases the rigidity of the ligand and reduces the loss of energy by radiation-less decay or vibrational motion [28,30], thus, the blue shift and enhanced luminescence intensities of the two compounds were observed.…”

Three new MOFs, namely [Ni(pip)(H 2 O) 2 ] (1), [Ba(pip)(H 2 O)] (2), [Zn(pip)] (3), based on 6-(3-pyridyl)isophthalic acid (H 2 pip) were obtained and characterized by single-crystal X-ray diffraction, elemental analyses, PXRD, IR and TGA. By adjusting the reaction solvent, temperature and selecting different metal centers, compounds 1 and 2 possess 1D and 2D network, respectively, compound 3 show a 3D network containing a paddlewheel secondary building unit [SBU, Zn 2 (COO) 4 ] with the Schläfli symbol (4Á6 2 ) 2 (4 2 Á6 10 Á8 3 ). The structural differences among compounds 1-3 exhibit the backbone of such mixed N-and O-donor atoms organic ligands can be used to construct diverse dimensional MOFs by adjusting the reaction environment. Furthermore, the luminescence properties of compounds 2 and 3 were investigated, and both of them exhibit intense fluorescent emissions in the solid state at room temperature.

“…Polycarboxylate ligands are among the most important organic building blocks and can act as reliable candidates for the assembly of various coordination species with interesting topologies and functional properties (Heinze & Reinhart, 2006;Jammi et al, 2008). It should be noted that rigid substituted isophthalic acids, such as 5-R-isophthalic acids (5-R-H 2 ip, R is the substituted group), have already been used extensively in the preparation of various novel MOFs with interesting architectures and properties (Zhang et al, 2014). The results show that the 5-R-ip 2À ligand in related coordination compounds has flexible conformations, various binding modes and a strong ability to form supramolecular interactions, such as hydrogen bonds andstacking interactions (Chang et al, 2012).…”

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.
