The diverse structures exhibited by complexes of p-block (Group 13-15) halides with acyclic and macrocyclic thio-, seleno-, and telluro-ethers are described. Examples range from six-coordinate monomers through to one-, twoor three-dimensional network infinite polymers with structural motifs often very different to those found with d-block elements.
BondingAlthough it has received much less theoretical effort than in transition metal analogues, bonding in main group complexes where the octet rule is formally exceeded, has attracted considerable recent interest. The original model invoking nd orbital involvement leading to for example, central atom sp 3 d 2 bonding Bill Levason obtained his BSc and PhD from UMIST and was appointed to a lectureship in Southampton in 1976, promoted to senior lecturer 1988, reader 1994 and Professor of Inorganic Chemistry in 1999 His research interests include the synthesis and coordination chemistry of selenium, tellurium, antimony and bismuth donor ligands, early transition metal chemistry, main group coordination chemistry, and heteropolyanions. He has co-authored over 300 research papers.
Bill LevasonGill Reid gained her BSc and PhD from the University of Edinburgh. Following a postdoctoral fellowship, she took up a lectureship in Inorganic Chemistry at the University of Southampton in 1991 and was promoted to senior lecturer in 1999. Her research interests are wide-ranging, encompassing many aspects of macrocyclic, transition metal and main group coordination chemistry, including the synthesis of macrocyclic and polydentate ligands involving Group 15 (P and As) and Group 16 (S, Se and Te) donor atoms, studies of their coordinating properties with metal ions and organometallic fragments and the synthesis and properties of metallocyclic species. She has co-authored over 120 research papers on aspects of this work.
