The occurrence and representation of three-centre two-electron bonds in covalent inorganic compounds

3-Centre 2-electron (3c–2e) interactions can be classified according to whether the pair of electrons are provided by two atoms (Class I) or by one atom (Class II). Recognizing that compounds with symmetrically bridging carbonyl ligands can belong to Class II provides a simple rationalization of the absence of M–M bonds in molecules such as Fe2(CO)9 and [CpFe(CO)2].

A simple method for the containment and purification of filled open-ended single wall carbon nanotubes using C60 molecules

Materials encapsulated inside opened SWNTs can be sealed using fullerenes as “corks”, to block the ends and thereby provide a way to remove the excess of external soluble material present after the filling step.

Directly observed covalent coupling of quantum dots to single-wall carbon nanotubes

About this collection

Malcolm was born in Eastleigh, Hampshire, on the 16th of April, 1936.  He received his B. Sc. (Hons) in 1956 from the University of London (Acton Technical College) and his Ph. D. in 1959 from Imperial College of Science and Technology, where he studied under Professor Sir Geoffrey Wilkinson.  Following Imperial College, Malcolm moved to Cambridge University in 1960, and finally to Oxford University in 1963, where he was appointed University Lecturer and Septcentenary Fellow in Inorganic Chemistry at Balliol College.  On the 2nd of January 1965, he married Jennifer Green (née Bilham), with whom he has also enjoyed a long time scientific collaboration.  Malcolm became a Fellow of the Royal Society in 1985 and was appointed Statutory Professor and Head of the Inorganic Chemistry Laboratory and Professorial Fellow of St. Catherine's College in 1989.  He became a research active Emeritus Professor in 2003 and continues to publish to this day.

Malcolm’s contributions to inorganic chemistry are numerous and varied.  His first publication, which bears the title “Bis cyclopentadienylrhenium hydride”,  appeared in 1958 and was based on his Ph. D. thesis which was entitled “A study of some transition metal hydrides and olefin complexes.”  To date, he has published more than 600 papers describing synthetic, structural, and mechanistic aspects of the chemistry of virtually every transition element.  In order to give the reader a flavour of the research that Malcolm has performed, the present collection provides a selection of his papers that have been published in journals of the Royal Society of Chemistry over a period of more than fifty years.  For example, these papers show how Malcolm’s research popularized the now ubiquitous molybdenocene and tungstenocene systems which provided evidence for alpha  and beta hydrogen migratory insertion reactions, and also early examples of C–H bond activation.  Read the full commentary here.
