“…3, 4 The resulting supramolecular structures in which counterions act as mediators between the SBUs are strongly influenced by the shape of the organic ligands. Here we report an important expansion of this work that demonstrates that our findings are not restricted to one particular SBU; moreover they are valid for negatively charged metal complexes where the ligands, containing separated hydrophilic and hydrophobic moieties, point rigidly in defined directions of space.…”

“…We are interested in these dense hexagonal arrays in compounds containing vast separated hydrophilic and hydrophobic areas and have previously used a similar Fe III compound as a template for the preparation of nanostructured fibrous materials, carbon-based microcapsules and sodium iron oxides. 4 A detailed account that investigates the thermolysis behaviour of 1 to give nanostructured cuprates and a comparison of its template effect with that of its corresponding Fe III compound will be reported elsewhere.…”

Hybrid organic-inorganic coordination assemblies are synthesized using modified aminocarboxylic acid ligands as the structure-directing agents. The synthetic approach results in two novel dinuclear copper(II) complexes, K2[CuII(hnida)]2.2H2O (1) and K4[CuII(chnida)]2.4H2O.4MeOH (2) that assemble in the presence of suitable counterions into a densely packed hexagonal array or an open-framework structure. The functionality of the aminocarboxylic acid ligands provides a tool to control the supramolecular structure. The materials combine promising thermal stabilities with the necessary flexibility to withstand structural changes induced by calcinations or the uptake and release of guest molecules. The structural and physicochemical properties of the complexes were investigated using X-ray diffraction, magnetic measurements, thermogravimetric analysis and spectroscopy.

“…Supramolecular metal structures have also been used as useful precursors for nanostructured metal oxides. For instance, Na 6 [Fe 2 (µ-O)(µ-CO 3 )-(chnida) 2 ]•13.5H 2 O (1; chnida = N-[(3-carboxy-2-oxy-naphthyl)methylene]iminodiacetate), after heating at 1100 • C affords nanoparticles of NaFeO 2 [44].…”

Nanomaterials have attracted much attention over the last decades due to their very different properties compared to those of bulk equivalents, such as a large surface-to-volume ratio, the size-dependent optical, physical, and magnetic properties. A number of solution fabrication methods have been developed for the synthesis of metal and metal oxides nanoparticles, but few solid-state methods have been reported. The application of nanostructured materials to electronic solid-state devices or to high-temperature technology requires, however, adequate solid-state methods for obtaining nanostructured materials. In this review, we discuss some of the main current methods of obtaining nanomaterials in solid state, and also we summarize the obtaining of nanomaterials using a new general method in solid state. This new solid-state method to prepare metals and metallic oxides nanostructures start with the preparation of the macromolecular complexes chitosan·Xn and PS-co-4-PVP·MXn as precursors (X = anion accompanying the cationic metal, n = is the subscript, which indicates the number of anions in the formula of the metal salt and PS-co-4-PVP = poly(styrene-co-4-vinylpyridine)). Then, the solid-state pyrolysis under air and at 800 °C affords nanoparticles of M°, MxOy depending on the nature of the metal. Metallic nanoparticles are obtained for noble metals such as Au, while the respective metal oxide is obtained for transition, representative, and lanthanide metals. Size and morphology depend on the nature of the polymer as well as on the spacing of the metals within the polymeric chain. Noticeably in the case of TiO2, anatase or rutile phases can be tuned by the nature of the Ti salts coordinated in the macromolecular polymer. A mechanism for the formation of nanoparticles is outlined on the basis of TG/DSC data. Some applications such as photocatalytic degradation of methylene by different metal oxides obtained by the presented solid-state method are also described. A brief review of the main solid-state methods to prepare nanoparticles is also outlined in the introduction. Some challenges to further development of these materials and methods are finally discussed.

“…bi-layer membranes. 22 In related experiments we succeeded in producing highly aligned Na2CO3 containing nanofibres that are contained in carbon microcontainers which form upon thermolysis within a single crystal of a coordination network containing the starting components for the mineralization in a pre-arranged form; 23 some of the investigated transition metal complexes have the ability incorporate carbonate ligands that form upon fixation of atmospheric CO2. 24 The presented study explores the role of the hda ligand system on the formation of supramolecular Ca-based coordination assemblies and its influence as a habit modifier for the bio-inspired preparation of crystalline CaCO3 materials.…”

A bio-inspired synthetic approach to unprecedented hybrid supramolecular assemblies [Ca(Mehda)(HO)]·HO (1) and [Ca(Chda)(HO)]·HO (2), that are stabilized by iminodiacetate-substituted organic ligands is reported. The results of the single-crystal X-ray analysis of 1 further allowed the use of electron microscopy to verify the supramolecular structure of the fibrous assemblies of 2 that incorporate extended alkyl-substituted ligand derivatives. 2 reveals interesting features that distinguish these soft structures from purely inorganic, brittle materials: meshes of nanobelts transform on solid supports to form homogeneous films covering extended, micro-sized areas. The use of the reported ligand system as a habit modifier for CaCO results in hierarchical calcite aggregates. The structure-influencing effects of the ligands and their supramolecular assemblies promote the formation of calcite disks that tessellate into hollow microspheres that contain distinctive openings.
