Book Description
The recent discovery of a biologically beneficial role for Cd(II) has motivated further investigation of its coordination chemistry. In this work, multidentate ligands model the geometric constraints associated with protein metal binding environments. The synthesis and characterization of Cd(II) complexes in a 1:1 ratio with 2-[[2-(dimethylamino)ethyl]amino]ethanethiol (HL1), Bis(2-methylpyridyl)diselenide (L2), and tris[(1-methyl-2-imidazolyl)methyl]amine (L3) may contribute to a better understanding of potentially biologically relevant interactions between Cd(II) and imidazoles, thiolates, selenoethers and diselenides. Three new complexes were synthesized and characterized. Electrospray ionization mass spectrometry of [(Cd(L1))6([micro]3-CO3)](ClO4)2 demonstrated that aromatic nitrogen donors are an optional component of NNʹS tridentate ligands forming Cd(II) complexes with CO2 fixating properties. The new complex [Cd(L2)(NO3)2] was prepared and characterized by X-ray crystallography, confirming that Cd-(Se2R2) bond formation could be fostered by a chelating ligand. Finally, structural characterization of the new complex [Cd(L3)(NCCH3)](ClO4)2 revealed a great deal of similarity to the coordination environment of Zn(II) in human carbonic anhydrase B.

Book Description
This Special Issue came together thanks to contributions from friends and colleagues of Prof. Bernd Giese on behalf of his 80th birthday on 2 June 2020. Reflecting on the varied interests of Bernd in all areas of chemistry, this issue contains work, including historical work, on inorganic coordination chemistry, nanomaterials, theory, and organic and radical chemistry—Bernd’s core expertise. It is wonderful that so many different publications came together from all over the world, as both review articles and original contributions, making this Special Issue worthwhile reading.

Book Description
Increasing the potency of therapeutic compounds, while limiting side-effects, is a common goal in medicinal chemistry. Ligands that effectively bind metal ions and also include specific features to enhance targeting, reporting, and overall efficacy are driving innovation in areas of disease diagnosis and therapy. Ligand Design in Medicinal Inorganic Chemistry presents the state-of-the-art in ligand design for medicinal inorganic chemistry applications. Each individual chapter describes and explores the application of compounds that either target a disease site, or are activated by a disease-specific biological process. Ligand design is discussed in the following areas: Platinum, Ruthenium, and Gold-containing anticancer agents Emissive metal-based optical probes Metal-based antimalarial agents Metal overload disorders Modulation of metal-protein interactions in neurodegenerative diseases Photoactivatable metal complexes and their use in biology and medicine Radiodiagnostic agents and Magnetic Resonance Imaging (MRI) agents Carbohydrate-containing ligands and Schiff-base ligands in Medicinal Inorganic Chemistry Metalloprotein inhibitors Ligand Design in Medicinal Inorganic Chemistry provides graduate students, industrial chemists and academic researchers with a launching pad for new research in medicinal chemistry.

Book Description
A concise introduction to the chemistry and design principles behind important metal-organic frameworks and related porous materials Reticular chemistry has been applied to synthesize new classes of porous materials that are successfully used for myraid applications in areas such as gas separation, catalysis, energy, and electronics. Introduction to Reticular Chemistry gives an unique overview of the principles of the chemistry behind metal-organic frameworks (MOFs), covalent organic frameworks (COFs), and zeolitic imidazolate frameworks (ZIFs). Written by one of the pioneers in the field, this book covers all important aspects of reticular chemistry, including design and synthesis, properties and characterization, as well as current and future applications Designed to be an accessible resource, the book is written in an easy-to-understand style. It includes an extensive bibliography, and offers figures and videos of crystal structures that are available as an electronic supplement. Introduction to Reticular Chemistry: -Describes the underlying principles and design elements for the synthesis of important metal-organic frameworks (MOFs) and related materials -Discusses both real-life and future applications in various fields, such as clean energy and water adsorption -Offers all graphic material on a companion website -Provides first-hand knowledge by Omar Yaghi, one of the pioneers in the field, and his team. Aimed at graduate students in chemistry, structural chemists, inorganic chemists, organic chemists, catalytic chemists, and others, Introduction to Reticular Chemistry is a groundbreaking book that explores the chemistry principles and applications of MOFs, COFs, and ZIFs.

Book Description
Scientific Study from the year 2018 in the subject Chemistry - Anorganic Chemistry, grade: 10, , language: English, abstract: Nanoscience is the study of phenomena exhibited by materials at atomic, molecular and macromolecular levels, of dimensions ranging from a few nanometres to less than a hundred nanometres. In chemistry, this size range has been associated with colloids, micelles, polymer molecules and similar structures. In physical and electrical engineering, nanoscience is often associated with quantum behaviour, and electron behaviour in nanoscale structures. The area of research in the field of nanotechnology is as diverse as physics, chemistry, material science, microbiology, biochemistry and also molecular biology. The interface of nanotechnology in combination with biotechnology and biomedical engineering has emerged with the use of nanoscale structures in diagnosis, gene sequencing, and drug delivery. Nanoparticles have attracted great interest in recent years because of their unique chemical and physical properties, which are different from those of either the bulk materials or single atoms. Nanostructure materials have potential applications in ceramics, optoelectronics and catalysis. Research on the synthesis of nanomaterials using metal complexes as precursors have been less reported. Application of metal complexes as precursors may be helpful to control the physical properties of metal nanoparticles. In the last few years, researchers have characterized the tunable properties by altering the nanostructure size, shape, and chemical composition and have developed reproducible strategies to make nanostructures of desired properties. It has been already proved that by controlling the size of the particle and manipulating surface structures of the semiconductor materials, the electronic, magnetic, mechanical, and chemical properties can be modified to suit a wide range of device application in many fields. The present book deals with the synthesis of Schiff base complexes of Cd(II), Zn(II) and Hg(II) with different sulphur containing ligand and preparation of metal sulphide nanoparticle by the thermal decomposition of complex precursor. During this academic journey four new sulphur containing ligands and their thirty complexes were synthesized. These ligands and complexes were characterized by spectroscopic methods like UV-Vis, FT-IR, 1H-NMR, 13C-NMR, 2D-NMR, FAB-MS / ESI-Ms spectra.
