Springer, 2003. — 269 p.Despite more than 200 years of sulfur research the chemistry of elemental sulfur and sulfur-rich compounds is still full of whitespots which have to be filled in with solid knowledge and reliable data.This situation is particularly regrettable since elemental sulfur is one of the most important raw materials of the chemical industry produced in record-breaking quantities of ca. 35 million tons annually worldwide and mainly used for the production of sulfuric acid. Fortunately, enormous progress has been made during the last 30 years in the understanding of the yellow element. As the result of extensive international research activities sulfur has now become the element with the largest number of allotropes, the element with the largest number of binary oxides, and also the element with the largest number of binary nitrides. Sulfur, atypical non-metal, has been found to become a metal at high pressure and is even superconducting at 10 K under a pressure of 93 GPa and at 17 K at 260 GPa, respectively.This is the highest critical temperature of all chemical elements. Actually, the pressure-temperature phase diagram of sulfur is one of the most complicated of all elements and still needs further investigation. Sulfur compounds have long been recognized as important for all life since sulfur atoms are components of many important biologically active molecules including aminoacids, proteins, hormones and enzymes. All these compounds take part in the global geobiochemical cycle of sulfur and in this way influence even the earths climate. In interstellar space, on other planets as well as on some of their moons have elemental sulfur and/or sulfur compounds also been detected. The best known example in this context is probably Iupiters moon Io, first observed by Galileo Galilei in 1610, which according to modern spectroscopic observations made from the ground as well as from spacecrafts is one of the most active bodys in the solar system with quite a number of sulfur volcanoes powered by sulfurdioxide and spraying liquid sulfur on to the very cold surface of this moon. The general importance of sulfur chemistry is reflected in the long list of monographs on special topics published continuously, as well as in the huge number of original papers on sulfurrelated topics which appeare very year. Regularly are international conferences on organic and inorganic sulfur chemistry held, and specialized journals cover the progress in these areas.ContentsQuantum-Chemical Calculations of Sulfur-Rich Compounds Molecular Spectra of Sulfur Molecules and Solid Sulfur Allotropes Inorganic Polysulfanes H2Sn with n 1 Inorganic Polysulfides Sn2– and Radical Anions Sn– Polysulfido Complexes of Main Group and Transition Metals Sulfur-Rich Oxides SnO and SnO2 Author Index Volumes 201–231 Subject Index Vol.230 Subject Index Vol.231
