The Aminoff Prize 2013

September 12, 2012

STOCKHOLM, September 13, 2012 /PRNewswire/ –

The Royal Swedish Academy of Sciences (RSAS) has awarded the Gregori Aminoff Prize in
Crystallography 2013 to:

        Carlo Gatti
        Institute of Molecular Sciences and Technology, Italian National Research Council
         (CNR-ISTM)
        Milan, Italy
        and
        MarkSpackman
        University of Western Australia
        Crawley, Australia

“for developing experimental and theoretical methods to study electron density in
crystals, and using them to determine molecular and crystalline properties”.

Nature of crystals measured by X-rays and interpreted in Italy and Australia

Crystallography is the science of the arrangement of atoms in solid materials. To
reveal the atomic structure of a crystal, an ‘X-ray diffraction method’ may be used. In
this method an X-ray beam strikes a crystal, showing a diffraction pattern that, in turn,
can be transformed into a 3D model of the crystal. This technique is now widely used in
geology, physics, chemistry, biology, medicine and materials engineering. Purposes include
determining mineral properties, proteins and DNA structures, and developing strong new
materials.

Both Carlo Gatti and Mark Spackman have independently developed concepts for
interpreting electron density distributions related to quantum chemistry theory, using
multipole analysis of high-quality X-ray diffraction data. This approach has, in
particular, significantly demonstrated and quantified the role of hydrogen bonding in
molecular systems. ‘Charge density topology’ is important for classification of the type
and strength of chemical bonding in solid compounds and molecules.
