The structural characteristics and the relation to the electronic properties of three types of molecular materials are discussed. In TMTSF2X salts a triclinic unit cell it suggested to be important in avoiding a 2kF Peierls distortion. In polythiophenes appropriate ordering of microcrystallites enhances the carrier mobility, and in pro chiral molecules the molecular characteristics give rise to a modulated polar structure.
