This volume summarises recent developments and highlights new
techniques which will define possible future directions for small
molecule X-ray crystallography. It provides an insight into how
specific aspects of crystallography are developing and shows how
they may interact or integrate with other areas of science. The
development of more sophisticated equipment and the massive rise in
computing power has made it possible to solve the three-dimensional
structure of an organic molecule within hours if not minutes. This
successful trajectory has resulted in the ability to study ever
more complex molecules and use smaller and smaller crystals. The
structural parameters for over a million organic and organometallic
compounds are now archived in the most commonly used database and
this wealth of information creates a new set of problems for future
generations of scientists. The volume provides some insight into
how users of crystallographic structural data banks can navigate
their way through a world where "big data" has become the norm. The
coupling of crystallography to quantum chemical calculations
provides detailed information about electron distributions in
crystals affording a much more detailed analysis of bonding than
has been possible previously. In quantum crystallography, quantum
mechanical wavefunctions are used to extract information about
bonding and properties from the measured X-ray structure factors.
The advent of quantum crystallography has resulted in form and
structure factors derived from quantum mechanics which have been
used in advanced refinement and wavefunction fitting. This volume
describes how quantum mechanically derived atomic form factors and
structure factors are constructed to allow the improved description
of the diffraction experiment. It further discusses recent
developments in this field and illustrates their applications with
a wide range of examples. This volume will be of interest to
chemists and crystallographers with an interest in the synthesis,
characterisation and physical and catalytic properties of
solid-state materials. It will also be relevant for the community
of computational chemists who study chemical systems. Postgraduate
students entering the field will benefit from a historical
introduction to the way in which scientists have used the data
derived from crystallography to develop new structural and bonding
models.
