Almost all branches of chemistry and material science now interface with organometallic chemistry - the study of compounds containing carbon-metal bonds. This widely acclaimed serial contains authoritative reviews that address all aspects of organometallic chemistry, a field which has expanded enormously since the publication of Volume 1 in 1964. Volume 56 comprises Part 1 of a themed collection of papers on "The Organotransition Metal Chemistry of Poly(pyrazolyl)borates".
