Research Interests: X-ray structural studies on inorganic, organic and organometallic compounds; hydrogen bonding; molecular modelling and charge densities.
Research is principally in the field of single crystal X-ray diffraction which is used to examine the structural chemistry, packing dynamics, fine detail of the bonding electron density (charge densities) and reaction mechanisms of a wide variety of compo unds. Currently, increasing emphasis is being placed on data collection at low temperatures which is needed if the details of the valence electron density is to be seen. Major projects underway at the moment include studies of the bonding and non-bonding electron density in phosphorus systems.
This is an attempt to provide experimental observations to test recent theoretical predictions. Another project is an examination of the complementary roles of hydrogen bonding and crystal packing energies in a s equence of systems formed between complex anions and cations. The purpose of this work is to establish the rules controlling the formation of such crystals and thus design materials with particular physical properties. There is an on-going study of tellur ium chemistry which includes both a detailed study of "simple" anions such as TeCl62- and the mechanisms for some unusual organo-tellurium reactions.
There are also studies of structures and mechanisms in novel main group chemistry, sulphone chemistry as well as a few selected topics in organometallic chemistry. The group has several diffractometers, a new Rigaku AFC5R on a rotating anode X-ray generator, two CAD4's and an in-house rebuilt Picker which operates on the Rigaku data- collection system. Th e computing is provided by a VAX 7600 workstation and there is a full suite of crystallographic programs TEXAN, SHELXL, CRYSTALS, MOLLY, etc. Molecular mechanics calculations are served by the latest version of CHEMX.
