About the Cover The c rystal structure of boggsite, a recently discovered natural zeolite, is composed of sodium, calcium, aluminum. si licon. hydrogen. and oxygen. Its unique a tomic structure of ten and twelve rings was determined by J. J . Pluth and J . V. Smith, geophysicists at the University of Chicago.

The new authors bri ng to the book their interests in coordination chemistry, organometallics, and physical methods, as well as fresh viewpoints on a number of other topics. Nevertheless. the philosophy of the book remains unchanged: To bring to the reader Appendix G Tanabe-Sugano Diagrams A-38 the essentials of inorganic chemistry in an easily readable format with emphasis on the fac t that inorganic chemistry is a n exciting field of research rather than a closed body of knowledge.

One of us received a B.S. degree from a Ph.D. granting institution, one from a private non-Ph. D. liberal arts college , and one from a public non-Ph.D. liberal arts college. We have taught under- graduate and graduate inorganic courses in a varie ty of settings. When we sat down to Appendix I The Rules of Inorganic Nomenclature A-46 discuss the revision, there were <t number of things that we agreed upo n: ( I ) The book would be substantiall y updated. (2} The material presented would continue to be thoroughly referenced, and the references would continue to appear on the pages of interest. A relevant reference would not be omitted just because it had appeared in Index A-78 previous editions. (3) New illustrations, many from the original literature, would be added. (4} A greater selection of problems, many of them new, would be provided . Many problems would requ ire library assistance, while others would cover the funda- mental aspects of each topic . (5) A chapter on symmetry would be added. (6} Solid state chemis try would be given more emphasis. (7) The kinetics chapter would be more fully developed. (8} The descri ptive and organometa llic chemistry of the lan- thanides and actinides would be included in the corresponding chapters fo r the transition metals. General consensus (among both authors and users) comes more easily than agreement on specifics. Our discussions of the symmetry chapter are a good example. All of us agTeed that the teaching of symmetry considera tions at most institutions had xi I Il i xii Preface Preface xiii ,l for the most part been delegated to the inorganic chemists.

But that means that it is balanced and should work equally well for a one-semester course- the instructor must pick and choose. We firmly believe that it is more useful to provide a large number of topics, wherein one can select the topics lobe covered, than to dictate a " minimum core ." We hope the book includes the topics that all instructors find essential. but we hope that it also includes their favorite topics. It obvious ly tncludes ours. A solutions manual that contains answers to all end-of-chapte r problems nccompanies the fourth edition. We would like to thank our colleague> at the Univers ity of Maryland at College Park (UMCP) and Eas tern Illinois Universit y (E IU) who have he lped in a multllude of ways. Professor Huhecy's colleagues who helped with previous editions are listed in the "Excerpts from the Preface to the Third Edition" (page xvi). and their further help is gratefully acknowledged. In addition. we would like to thank Bryan Eichhorn (UMCP), William Harwood (UMCP). Ma rk McGuire (EIU). Robert Pilato (UMCP), and Rinaldo Poli (UMCP) for special help with this edition . We would also like to To the Student xv limiting each topic to a few paragraphs. This has the adv;mtage of including most topics but the disadvantage of having to look elsewhere for a fu ller development. Any single book, of course. has this problem to a certain degree, thus the need for m~ny references . Our book, Inorganic Chemistry: Principles of Strucl/lre and ReactiVIty, fourth edition . is also a blend of fact and theory, but we think it is large enough for a full meal. There is no reason to expect a book that deals with the chemistry of 109 e lements to be smaller than a standard organic chemistry textbook! To the Student We've enjoyed writing this book; we hope that you will enjoy reading it. lf you do, we'd like to hear from you. James E. Huheey Ellen A. Keiter Richard L. Keiter Once after a departmenta.J seminar, an older professor was heard to remark lhat he fell intimidated by all of the new theory and experimental spectroscopic methods known by the new chemistry graduates. A young graduate student was stunned: she was sure it would take her years just to Jearn enough of the chemistry that he already knew to get her degree. Meanwhile , two other professors were arguing heatedly over the relative importance of facts versus theory. One said descriptive chemistry was the most important because "facts don't change!'' "Well, some 'facts' seem to c hange- I read yesterday that iridium is the densest element: ten years ago when I was a student , I was told that osmium was the densest." "They don 't change as fast as theories; theories just come and go; besides, what's wrong with someone repeating an experiment and doing it beuer-gelling a more accurate value?" "That's the point; new theories are necessary to explain new experimental data, and theories give us something to test, a framework around which we can dream ..." "Dream! We need a lillie less 'inspiration' and a lot more perspiration ... " And so it goes .. .. These chemists and these arguments present a microcosm of perpetual debates in c hemistry and the essence of the great difficulty in writing an upper level textbook of inorganic chemistry. The field is vast: large numbers of inorganic articles are published every week. New synthetic techniques a llow the isolation and identification of great numbers of highly reactive compounds. The- oretical descriptions have become increasingly sophisticated. as have spectroscopic methods. Inorganic che mistry interacts with organic. physical, and even biological chemistry. Borderlines between molecular and solid-state chemistry are rapidly disap- pearing. The older chemist may know many facts and theories but realizes it is only a small portion of the whole. The new graduate, with well-developed skills in a few areas, also has a sense of inadequacy. Perhaps the s tudent faced with his or her first advanced inorganic course feel s this most acutely. The textbook for the course reOects the instructor's choice of what portion of inorganic chemistry should be taught, what mix of fac ts a nd theory. a nd what relative weight of traditional and new science. Authors also make their choices and those are seen in the variety of available textbooks on the market. Some are heavily fact ual, usually bulky, and especially useful for finding out something about all of the principal compounds of a particular xiv element. Others present a blend of fact and theory but minimize the book bulk by
