This unique book provides comprehensive coverage of monocyclic inorganic ring systems of the p-block elements and the polymers that are derived from them. The book deals firstly with the fundamentals covering the following topics - synthetic methods, characterisation techniques, delocalisation in inorganic rings, paramagnetic inorganic rings, inorganic macrocycles, ligand chemistry and inorganic polymers. The next chapters discuss in detail the chemistry of inorganic homo- and heterocycles involving the elements of groups 13-16 (the p-block elements). The book is intended primarily for senior undergraduates and graduate students in inorganic chemistry and research workers, it also provides a suitable introduction and overview for chemists who are not working directly in the field.
