To prepare nanoscale coordination polymers (NCPs) which can exhibit intense luminescence have attract an increasing interest. In this paper, we present the synthesis of a novel example of discus-like luminescent nanoscale Eu (III)-carboxylate coordination polymers. The organic ligand is a derivative of terephthalate (Na2L) with a big side group. The Eu (III)-L NCPs was synthesized through microemulsion method, and the morphology can alter along with the changing of metal: ligand ratios. XRD results reveal that the self-assembled disk-like NCPs exhibit long-range ordered structures. The luminescent measurements showed that the resultant NCPs not only exhibits typical fluorescence of Eu (III), but also can maintain the inherent fluorescence of the ligands.

Metal–organic frameworks (MOFs) are a family of porous crystalline materials that serve in some cases as versatile platforms for catalysis. In this review, we overview the recent developments about the use of these species as heterogeneous catalysts in olefin epoxidation and carbon dioxide cycloaddition. We report the most important results obtained in this field relating them to the presence of specific organic linkers, metal nodes or clusters and mixed-metal species. Recent advances obtained with MOF nanocomposites were also described. Finally we compare the results and summarize the major insights in specific Tables, outlining the major challenges for this emerging field. This work could promote new research aimed at producing coordination polymers and MOFs able to catalyse a broader range of CO2 consuming reactions.

Organic Networks

Metal organic networks (MONs) are defined as one, two and three dimensional unique complex structures of porous material and subclass of polymer’s coordination. These networks also show extreme surface area, morphology, excellent chemical stability, large pore volume, highly crystalline materials. The major advantages of MONs are tailorability, structural diversity, versatile applications, highly controllable nano-structures and functionality. So, the multi-functional applications of these MONs are made them more helpful tools in many fields of science in recent decade. In this paper, we light on the two different MONs with respect to the number of increasing layers of metal and organic ligands together. We define the novel multiplicative Zagreb connection indices (ZCIs) such that multiplicative fourth ZCI and multiplicative fifth ZCI. We also compute the main results for multiplicative Zagreb connection indices of two different MONs (zinc oxide and zinc silicate).

Organic ligands and counter-anions influence the coordination spheres of metal cations and hence the construction of coordination polymers (CPs). The specific bent geometries of five-membered heterocyclic triazole bridging organic ligands are capable of generating CPs with novel patterns not easily obtained using rigid linear ligands. A multidentate 4-aminotriazole-bridged organic ligand, namely 4-amino-3,5-bis(4,3′-bipyridyl-5′-yl)-4H-1,2,4-triazole (L) has been prepared and used to synthesize two CoII coordination polymers, namely poly[[[μ2-4-amino-3,5-bis(4,3′-bipyridyl-5′-yl)-4H-1,2,4-triazole-κ2 N:N′]bis(methanol-κO)cobalt(II)] bis(perchlorate)], {[Co(C22H16N8)2(CH3OH)2](ClO4)2} n , (I), and poly[[μ3-4-amino-3,5-bis(4,3′-bipyridyl-5′-yl)-4H-1,2,4-triazole-κ3 N:N′:N′′]dichloridocobalt(II)], [CoCl2(C22H16N8)] n , (II), using CoX 2 salts [X = ClO4 for (I) and Cl for (II)] under solvothermal conditions. Single-crystal X-ray structure analysis revealed that they both feature two-dimensional networks. Cobalt is located on an inversion centre in (I) and in a general position in (II). In (I), L functions as a bidentate cis-conformation ligand linking CoII ions, while it functions as a tridentate trans-conformation linker binding CoII ions in (II). In addition, O—H...N and N—H...O hydrogen bonds and C—H...π interactions exist in (I), while N—H...Cl and π–π interactions exist in (II), and these weak interactions play an important role in aligning the two-dimensional nets of (I) and (II) in the solid state. As the compounds were synthesized under the same conditions, the significant structural variations between (I) and (II) are believed to be determined by the different sizes and coordination abilities of the counter-anions. IR spectroscopy and diffuse reflectance UV–Vis spectra were also used to investigate the title compounds.

Structural Responses

As the number of framework materials known and characterized in the literature grows, it becomes apparent that they can carry properties rarely encountered in more conventional, dense inorganic materials. Among these materials with unusual physical or chemical properties are the ubiquitous metal–organic frameworks, covalent organic frameworks, dense coordination polymers, and molecular frameworks. Many can respond to stimulation by displaying structural responses and changes in properties that range from counter-intuitive to thermodynamically forbidden. In that, they share large similarities with metamaterials, which are engineered to generate properties not found in “normal” materials. We review here the surprising behavior of these meta-MOFs and other framework materials that display properties “beyond” (μετά) the boundaries of common crystalline materials.<br>

Several studies have aimed to better understand coordination polymers, which are structures based on a connection between a metal ion and an organic ligand that extends infinitely, forming a macro-structure1. The interest in this type of structure is mainly due to its properties, such as its pore-forming ability, presenting many potential applications2 like selective separations, catalysis and gas storage. It is interesting to study the structure of coordination polymers to focus in some particular future application. In these way, a coordination polymer was synthetized by simple mixture with isonicotinylhydrazine (INH) and 1,2,4,5-benzenetetracarboxylic acid (BTC) ligands and zinc metallic ion. Yellow single crystals were formed in solution and one was separated, measured and solved by single crystal X-ray diffraction. The crystal-data for the structure were collected using an Oxford GEMINI A-Ultra diffractometer with MoKα radiation (λ = 0.71073 Å) at room temperature and solved using SHELXL-97 program3. The compound crystallized in monoclinic crystalline system in space group P21/c, cell parameters: a=9.2502(6) Å, b= 15.0004(6) Å, c=9.2947(4) Å, β= 108.4590(6), V=1223,35 Å3and Z=4. The final statistical parameters of the structure refinement were R=0.0326, wR=0.0835 and S=1,053. In this compound the BTC and INH ligands are coordinated like a bridge to two zinc ions. The BTC forms chelates by two carboxylate groups and INH coordinates by pyridine ring and by chelate at hydrazide group. This polymer extends in only one direction along a axis forming a 1D network. There is only one metallic zinc ion crystallographically independent on structure, it is in a distorted octahedral geometry with oxygen and nitrogen atoms of ligands and one coordinated water molecule in its coordination sphere. The 1D network formed by coordination polymers stabilizes the crystalline arrangement by hydrogen bonds between carboxylate and hydrazide groups and coordinated water molecules.
