Urea-alcane inclusion compounds
We
are studying incommensurate composite structures made of an hexagonal
host urea lattice and guest alkane molecules which pile-up into
adjacent channels built from urea double helix. Most of these
compounds are aperiodic by construction. They exhibit original
properties such as a sliding mode or phase transition occuring in the
superspace. (

Topological analysis of electron density
- Use of topological analysis of the electron density was first proposed by R.F.W Bader.
In this approach one follows density gradient path and look for
critical points of the electron density. For instance saddle points
corresponds to chemical bonding and both qualitative and
quantitative informations can be obtained. On the other hand, unique
partitionning of space into atomic basins (zero flux surfaces) can be
drawn allowing, for instance, for intermolecular charge transfer
determination.
- We have developped, (collaboratrion with LCM3B University UHP, Nancy) a software package InteGriTy
wich perform topological analysis on electron densities given on grids,
as well as graphical tools to visualize critical points, bondpaths or
atomic basins
