“…Pb1 and Pb2 are seven-and fivefold coordinated, respectively, and form a distorted pentagonal bipyramidal (PbO 7 ) and a distorted square-pyramidal geometry (PbO 5 polyhedra). The Pb-O bond lengths are in the range of 225.3(12)-286.8 (12) pm which are in agreement with literature data. [35,44] Edge-sharing of the PbO 7 and PbO 5 polyhedra is observed which results in the formation of infinite zig-zag chains along the b axis.…”

A high-throughput (HT) investigation using the rigid bifunctional ligand 4-phosphonobenzenesulfonic acid, H 2 O 3 P-C 6 H 4 -SO 3 H (H 3 L), generated five new phosphonatobenzenesulfonates with copper(II) or lead(II) ions. A comprehensive HT study comprising the screenings of different metal ions, metal salt types and the synthesis optimization were conducted whereby the influence of pH and molar ratios M 2+

“…The Ti 2p line of the Ti-HEDP sample is composed of two single peaks situated at 459. 4 The amount of water and the thermal stability of Ti-HEDP were determined by thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC). The TGA curve shown in Figure 8 demonstrates an initial weight loss of 10.77 % from room temperature to 217°C, accompanied by an endothermal peak around 108°C in the DSC curve, which may be assigned to the desorption of the adsorbed and intercalated water.…”

An organic-inorganic hybrid nanostructured material of titania-diphosphonate (Ti-HEDP) was prepared from a simple self-assembly process with the precursor tetrabutyl titanate and 1-hydroxyethane-1,1-diphosphonic acid (HEDP). The prepared hybrid Ti-HEDP has a semicrystalline anatase phase, exhibiting a hierarchical macroporous structure composed of mesostructured Ti-HEDP nanorods with a length of 80-150 nm and a thickness of 18-38 nm. The BET surface area is 257 m 2 /g. The 1-hydroxyethane-1,1-diyl-bridged organophosphonate groups were homogeneously incorported

“…Such inorganic hybrid materials are of particular interest for their structural architectures [24][25][26][27][28] and potentially useful gasadsorption characteristics. [29] Liao et al [15] have recently shown that a choline chloride/urea mixture can be used to prepare a zinc organophosphate where ammonium acts as the temple. Our work herein shows that we can control whether or not templating takes place by judicious choice of the eutectic solvent.…”

Ionothermal Materials Synthesis Using Unstable Deep‐Eutectic Solvents as Template‐Delivery Agents

et al. 2006

The use of organic templates (also called structure-directing agents) remains one of the most successful methods of preparing new inorganic materials. [1,2] Many of the most important recent advances in porous solids in particular depend on the clever use of organic species as templates to produce new zeolites, [3][4][5] transition-metal phosphates [6] or oxides, [7] and to make synthetic methods more efficient.[8]Ionothermal synthesis, where an ionic liquid is both the solvent and source of the template, provides opportunities to develop new synthetic routes that are based on different chemistry to traditional hydrothermal approaches. [9][10][11][12] Herein we describe the controlled use of deep-eutectic solvents (DESs) that are unstable at high temperatures as the media for ionothermal reactions. The organic template is not added to the reaction mixture in the normal way, but is delivered to the reaction by the breakdown of one of the components of the DES itself, demonstrating how the unique solvent properties of these ionic liquids can be harnessed to produce new types of solid.A DES is a mixture of two compounds where there is a depression in the freezing point of the mixture compared with that of the separate components. One class of DES comprises mixtures of organic halide salts with hydrogen-bond donors, such as amides, amines, alcohols, and carboxylic acids. [13,14] The freezing-point depression in the mixture results from the formation of halide ion-hydrogen-bond-donor supramolecular complexes that alter the free energy of the solid phase compared to the liquid. DESs are therefore predominantly ionic liquids, with properties that differ markedly from those of molecular liquids and salts dissolved in molecular solvents. Such DESs have features that make them excellent choices
