The present volume is the first of a series describing acyclic sulfur-nitrogen compounds with sulfur of oxidation number IV. The acyclic sw-N compounds are arranged according to the coordination number of the sulfur. Neutral compounds are described before ions and complex compounds. The preceding series "Sulfur-Nitrogen Compounds" Parts 2, 3, and 4 covers the cyclic sw-N compounds. In this volume, the first section deals with sulfur-nitrogen compounds with 1-coordinate sulfur and begins with the sulfur nitride {thiazyl) radical, SN. This transient molecule was observed in its electronic ground state and several electronically excited states. The descrip tions of the sulfur nitride (thiazyl) ions SN+ and SW follow. The SN+ ionwas studied in the gas phase as weil as in the solid state where it forms salts. Thionitrosyl complexes containing the SN Iigand as a terminal linear unit are described at the end of the first section. The second section concerns Sulfur-nitrogen compounds with 2-coordinate sulfur and starts with the description of poly(sulfur nitride), (SNlx· The preparation, crystal structure, and metallic and superconducting properties of (SN)x, which were extensively studied, fill a !arge part of the volume. Halogen-modified poly(sulfur nitride) such as the widely studied (SNBr )x 04 and Na-modified poly(sulfur nitride) are dealt with in the following chapters.

The present volume describes cyclic sulfur-nitrogen compounds whose ring system con tains one or two other types of atoms in addition to sulfur and nitrogen. At least one sulfur atom can be regarded as having oxidation number IV in one resonance structure. That means the sulfur in fact has an oxidation number higher than 11 and lower than VI. The volume continues "Sulfur-Nitrogen Compounds" Part 2, in which the binary sulfur(lV)-nitrogen ring systems are described. Compounds with the same "hetero atom" in the sulfur-nitrogen ring are arranged in groups. Within a group the compounds are arranged according to ring size, and for a given number of ring atoms, in order of decreasing S: N ratio. Neutral compounds are described before ions, and saturated compounds before unsaturated, aromatic ones. A very heterogeneous material is brought together in this volume. SN Se2 rings, which 2 strongly resemble the binary S3N2 ring, are covered. S-N-Si rings with five, six, and eight atoms, and also N-S-N-bridged eight-membered rings, are described. The S-N-P rings form a puzzling and complex part of this volume; they readily interconvert by dimerization, cleavage, and by addition and loss of NSN and NPN groups. Especially interesting is the aromatic character of 8-N-P rings.

This volume treats the acyclic sulfur(II)-nitrogen compounds with one-coordinate and two-coordinate sulfur. Sulfur imide (S=NH) and N-organyl-sulfur imides (S=NR) are unstable compounds which can be stabilized by coordination to transition metals or trapped, for example, by Ä2 + 4Ü cycloaddition with 1,3-butadiene. Among dithionitryl (1+) salts, only ÄS=N=SÜ+AsF6- has been studied extensively. Cycloaddition with alkenes and triple bond compounds produce 1,3,2-dithiazolium salts. Thiohydroxylamine, HSNH2, has been detected in the gas phase. Numerous examples of N, N-diorganyl-amino-halogeno-sulfanes (XSNR2, X = F, Cl, Br, I; R = organyl) and salts of the cation (XS)2N+ (X = Cl, Br) are known. N, N-Diorganyl-amino-chloro-sulfanes are important synthetic reagents.

Chalcogen-nitrogen chemistry involves the study of compounds that exhibit a linkage between nitrogen and sulfur, selenium or tellurium atoms. Since the publication of A Guide to Chalcogen-Nitrogen Chemistry in 2005, the emphasis of investigations of chalcogen-nitrogen compounds has advanced from a focus on fundamental studies to the development of practical applications, as indicated by the title of this new edition. Pharmaceutical applications of organic sulfur-nitrogen compounds include drugs for the treatment of various diseases, as well as probes for locating tumour cells. From a materials perspective, carbon-containing chalcogen-nitrogen heterocycles have applications in everyday devices such as LEDs and solar cells. A new technology based on binary sulfur nitrides is being used for fingerprint detection in forensic science. As a result, this book includes seven new chapters and updates the others with extensive literature coverage of developments since 2005 while retaining earlier seminal results. This comprehensive text is essential for anyone working in the field, and the four introductory chapters emphasise general concepts that will be helpful to the non-specialist. The treatment is unique in providing a comparison of sulfur, selenium and tellurium compounds. Each chapter is designed to be self-contained, and there are extensive cross-references between chapters.

The volume continues the description of acyclic sulfur - nitrogen compounds with sulfur having the oxidation number II and covers amino-di- and aminopolysulfanes as well as diamino-di- and diamino-polysulfanes. Numerous examples of the class of diamino-disulfanes and their interesting chemical properties are described: N, N'-disulfanediyl-bis(N-heterocycles), for instance, undergo S-S bond scission in a thermal or photochemical radical - dimer equilibrium or react with acetylenes to give thiophenes, and N, N'disulfanediyl-bis(phthalimide) is a sulfur transfer reagent for organic synthesis. The volume completes the series on sulfur - nitrogen compounds which is a unique and comprehensive source of information for this field in chemistry.

The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.

The focus of the book is monocyclic inorganic ring systems of the p-block elements and the polymers that are, in many cases, derived from them. Bicyclic or polycyclic arrangements are considered when they are closely related to those of monocyclic systems.
