Reedijk, Netherlands Preface This book is intended to be an adjunct to the first volume which appeared in 1990 and which contains aims, grammar, basic tenets and main classes of nomenclature. For these basic aspects the reader is referred to the primary volume. The current volume is intended to deal with the nomenclature of systems which have specific difficulties with condensed phases such as solids or polymers and where various local nomenclatures have grown up to confuse the practitioners or those entering the fields of research. It addresses such diverse chemistry as polyanions, isotopic modification, tetrapyrroles, nitrogen hydrides, inorganic ring, chain, polymer, and graphite intercalation compounds. It is aimed at bringing order into the nomen- clature of these specialized systems based on the more fundamental nomenclature described in the primary volume and in the organic nomenclature publications. The volume is timely in relation to the growth of inorganic polymers especially and it is hoped that the practitioners will accept the orderly recommendations proposed and use it to simplify the literature espe- cially for the students who now begin to study such systems. The various chapters have been subject to extensive review not only by Commission members but also by practising chemists in the various areas over several years. The evolved chapters should therefore represent a consensus view of appropriate nomenclature for now and some years to come. The Commission is grateful to the external reviewers for their careful and critical comments and support to bring order into the nomenclature of such complex systems. Also, since the topics are largely unrelated and each has an Introduction or Pre- amble, no overall introduction is required and the reader is referred to the first volume for such general comments on nomenclature. 1st July, 2000 A S H D.
