Polymerized alkali fullerides KC{sub 60} and RbC{sub 60} display different electronic properties. Single crystal X-ray diffraction and diffuse scattering studies show that the C{sub 60} chains possess different relative orientations about their axes. We will discuss this result in relation with electronic band structure calculations. The influence of pressure will also be discussed. (c) 1999 American Institute of Physics.
