Book Description
The 3rd supplement continues the updating of the original 20 volumes on boron com pounds published between 1974 and 1979. The first supplement to this series brought the literature closing date uniformly to the end of 1977, whereas the two volumes of the 2nd supplement have extended the literature coverage of boron compounds to 1980. Selection and presentation of data parallel the style selected for the two previous supplement volumes, which appeared in 1980/1 and 1982/3, respectively. The Gmelin Principle of the Last Position is largely adhered to, excepting substituted polyboron species containing boron-boron bonds (all of which are found in Chapter 2 within the system boron-hydrogen). Examples of organic derivatives are included, especially in those cases where the carbon-free species are not known; and the carboranes are treated comprehensively. The literature is considered through 1984. Part 1 of the present 3rd supplement contains the systems boron-noble gases and boron hydrogen; Part 2 contains the system boron-oxygen. Part 3 will contain the systems boron nitrogen, boron-fluorine, and boron-chlorine; the remaining systems and a formula indexwill be included in the final 4th part of this supplement. The first chapter of the present volume on the compounds of boron and oxygen provides sections on the binary boron oxides, including some radicals, and the anhydrous berate ions. The following chapter describes boron-oxygen compounds with hydrogen or organyl groups.

Book Description
The present issue, Volume 3a of "Boron Compounds" 4th Supplement of the Gmelin Hand book, presents the description of boron nitride and a part of other boron compounds containing nitrogen. Volume 3 b (to be published Later) will complete the presentation of the boron-nitrogen compounds and will also cover boron compounds containing fluorine. Due to technical circumstances, Volume 1 (systems with hydrogen) and Volume 2 (systems with oxygen) of this particular supplement will be published subsequently, whereas Volume 4 (boron compounds containing CL, Br, I, S, Se, and Te, as well as a section containing carboranes) has already been published. ALL volumes of the 4th Supplement will be augmented by a formula index. The IUPAC nomenclature is generally adhered to; occasional abbreviations for compounds are explained in the text. A positive sign for the chemical shifts of the NMR signals indicates a 1 13 downfield shift from the references, usually internal (CH ) Si for 6 H and 6 C and external 3 4 11 (C H h0-BF for 6 B, others being specified. 2 5 3 In contrast to more recent publications but remaining consistent with the previous volumes of the Boron Series, the iminoborane structure is written as B=N and not as B=N. In fact, the real electronic structure is more realistically symbolized by B=N, but it seems reasonable to avoid =NR in accordance with the commonly accepted "iminoborane" nomenclature.

Book Description
The present issue, Volume 2 of "Boron Compounds" 4th Supplement of the Gmelin Hand book, updates the previous issues by reporting the literature on boron-oxygen systems published up to 1988. For some important recent developments literature is covered through mid-1992; this concerns, for example, the compounds ~-Ba3[B306h and U[B305J which became of interest as materials with nonlinear optical properties. The volume directly com plements the earlier "Boron Compounds" 3rd Supplement Volume 2. In the original literature, alternative formulations are frequently used for the same com pound. This is especially true for many borates. Often, these species are neither completely heteropolar nor covalent, and an experimentally based decision has not been made. Hence, the use of brackets does not necessarily reflect a truly salt-like character. Volume 1 (systems with hydrogen and noble gases) of this particular supplement will be published subsequently, whereas Volume 3a (boron and nitrogen), Volume 3b (boron and nitrogen, boron and fluorine), and Volume 4 (boron compounds containing Cl, Br, I, S, Se, and Te, as well as a section containing carboranes) have already been published. All volumes of the 4th supplement will be augmented by a formula index. The IUPAC nomenclature is generally adhered to; thf means tetrahydrofuran; and occa sionally additional abbreviations for compounds are explained in the text. Positive signs for chemical shifts of the NMR signals indicates downfield shifts from the references, usually internal (CH3)4Si for olH and 013C with others being specified.

Book Description
The first supplement volume eomplements the 20 volumes on boron eompounds (Borverbin dungen) that have been published within the New Supplement Series (Erg.-Werk) of the eighth edition of the Gmelin Handbook by uniformly updating the literature eoverage to the end of 1977. However, the deseription in this supplement volume follows largely the Gmelin prineiple of the last position. The systems boron-hydrogen and boron-oxygen were presented in the first part, the systems boron-nitrogen and boron-halogens in the seeond part. This third and final part eontains the systems boron-ehaleogens and also earboranes as weil as a formula index for the three parts of the first supplement volume. Besides the earboranes many additional examples of earbon-eontaining or organie eompounds are ineluded in the presentation, partieularly in those eases where the earbon-free speeies are not known. As was the ease in the volumes of the New Supplement Series, a substantial part of this supplement volume is already presented in the English language. The IUPAC nomenelature is adhered to as mueh as possible, deviations are elearly indieated. Unless otherwise noted, a positive sign for the ehemieal shifts of nuelear magnetie resonanee 1 13 signals indieates downfield from the referenees (CH3)4Si for 8 H and 8 C, (C H hO' BF for 2 5 3 11 14 31 8 B, aqueous NaN0 for 8 N, and 85% H P0 for 8 P.

Book Description
Provides an overview of the developments on the chemistry of the chalcogen group elements (S, Se and Te). Organised into two parts, this book deals systematically with the chemistry of chalcogens in relation to other group elements in the periodic table, and also includes an overview of metal-chalcogenides and metal-polychalcogenides.
