<br> The author explains the observed trends in the bonding and structure of molecules and solids within the framework of simple but predictive models of electronic structure. . . .Emphasis is placed throughout on recent theoretical developments that link structural stability to the local topology or connectivity of the lattice through the moments of the electronic density of states. . . .This modern real-space approach allows an immediate understanding of the origin of the structural trends within the periodic table for the elements and the AB structure map for binary compounds. --Zeitschriftf?r Kristallographie<p><br>
