KN 1: A theoretician's view of crystallography. Session Chair Joel Bernstein.

Roald Hoffmann, Ivano Bertini, Antonio Tiripicchio.

Roald Hoffmann receives the 2005 Sacconi Medal from Ivano Bertini. The Inorganic Chemistry Division of the Italian Chemical Society together with the Luigi Sacconi Foundation, on the occasion of the annual meeting of the Division, awards the Luigi Sacconi Medal to a scientist (Italian or foreigner) who has obtained particularly significant results in Inorganic Chemistry, the field in which Luigi Sacconi gave outstanding contributions.
