Book Description
This dissertation focuses on the challenge of developing porous metal arylphosphonates with both high crystallinity and functional porosity by using different synthetic approaches. Metal phosphonates are an extensive class of materials based upon extended inorganic-organic architectures such as chains, layers and three-dimensional networks. Metal phosphonates generally favor extended inorganic architectures leading to pillared materials with no porosity. We found that the use of template molecules, type of ligand and choice of metal ions could be used to deviate from the pillared structure. Many of these structures had interesting properties that were explored. The results can be divided into three areas: We developed non-pillared monovalent metal phosphonates by investigating both the role of water and template molecules in the solvothermal synthesis. The role of water in solvothermal reactions was found to have a profound influence on the structure of monovalent metal phosphonates and the structures could be tailored from zero/one-dimensional to two-dimensional. Non-pillared structures could be synthesized by using template molecules. For a zinc phosphonate, we converted a layered structure into a three-dimensional framework by using small template molecules in the solvothermal reaction. The compound exhibited reversible dehydration behavior. The change in the framework structure and guest positions was monitored during this process. Two different ligands were used in the development of porous aluminum phosphonates. One series exhibited reversible dehydration behavior, which had a dramatic influence on permanent porosity of the material. The stability of the dehydrated phase is a result of the geometry of the aluminum atom, which in some cases has coordinatively unsaturated metal sites. The second series was developed with ion exchange applications in mind therefore the pore environment was tailored to favor ion exchange processes. The most important aspect is that these compounds exhibit high selectivity for Th4+ ions. In total 28 new compounds were prepared, and their utility and structures clarified.

Book Description
Crystalline nanoporous materials like zeolites and metal phosphates (e.g. AlPOs) are used commercially for catalysis, adsorption, molecular sieving, and ion exchange. Their properties are related to both their porous architectures and chemical compositions. Materials that incorporate tin(II) and antimony(III), with stereochemically active lone electron pairs, could impart properties different from those of materials based on aluminum, cobalt, zinc, iron, and other metals that adopt [MO4] tetrahedra. Exploratory hydrothermal synthesis resulted in thirty new tin(II) and antimony(III) materials, including the first open-framework antimony(III) phosphate. Structure determination was by single crystal X-ray diffraction. Some materials incorporate a three-ring chain motif observed in other metal phosphates. Previously proposed metal phosphate formation mechanisms are shown not to adequately describe its formation. A new mechanism is proposed, adapting the Partial Charge Model of Livage, et al. to tin(II) and antimony(III) phosphates. This mechanism, starting from open chain metal phosphate 'wires' (with M-O-P bonds), is then extended to other metal phosphates.

Book Description
Metal phosphonate chemistry is a highly interdisciplinary field, as it encompasses several other areas, such as materials chemistry, gas storage, pharmaceutics, corrosion control, classical chemical synthesis, X-ray crystallography, powder diffraction, etc. It has also acquired additional significance due to "Metal-Organic Frameworks", as evidenced by the hundreds of papers published each year. This book fills the gap in the literature by summarising, in a concise way, the latest developments in the field. Metal phosphonate chemistry has seen impressive growth in the last 15-20 years and there is a clear need to systematize and organize all this growth. This unique book accomplishes just that need - edited by two experts, it includes contributions from other experienced researchers and organises, categorises and presents in an attractive way the latest hot topics in metal phosphonate chemistry and related applications. With an extensive bibliography, it is a great reference for academic and industrial researchers as well as students working in the field and will act as a starting point for further exploration of the literature. It is also of great interest to scientists working in the broader area of metal-organic frameworks and their applications.

Book Description
Comprehensive Inorganic Chemistry II, Nine Volume Set reviews and examines topics of relevance to today’s inorganic chemists. Covering more interdisciplinary and high impact areas, Comprehensive Inorganic Chemistry II includes biological inorganic chemistry, solid state chemistry, materials chemistry, and nanoscience. The work is designed to follow on, with a different viewpoint and format, from our 1973 work, Comprehensive Inorganic Chemistry, edited by Bailar, Emeléus, Nyholm, and Trotman-Dickenson, which has received over 2,000 citations. The new work will also complement other recent Elsevier works in this area, Comprehensive Coordination Chemistry and Comprehensive Organometallic Chemistry, to form a trio of works covering the whole of modern inorganic chemistry. Chapters are designed to provide a valuable, long-standing scientific resource for both advanced students new to an area and researchers who need further background or answers to a particular problem on the elements, their compounds, or applications. Chapters are written by teams of leading experts, under the guidance of the Volume Editors and the Editors-in-Chief. The articles are written at a level that allows undergraduate students to understand the material, while providing active researchers with a ready reference resource for information in the field. The chapters will not provide basic data on the elements, which is available from many sources (and the original work), but instead concentrate on applications of the elements and their compounds. Provides a comprehensive review which serves to put many advances in perspective and allows the reader to make connections to related fields, such as: biological inorganic chemistry, materials chemistry, solid state chemistry and nanoscience Inorganic chemistry is rapidly developing, which brings about the need for a reference resource such as this that summarise recent developments and simultaneously provide background information Forms the new definitive source for researchers interested in elements and their applications; completely replacing the highly cited first edition, which published in 1973
