The KC{sub 60} and RbC{sub 60} polymer phases exhibit contrasting electronic properties while powder diffraction studies have revealed no definite structural difference. We have performed single crystal x-ray diffraction and diffuse scattering studies of these compounds. It is found that KC{sub 60} and RbC{sub 60} possess different chain orientations about their axes, which are described by distinct space groups Pmnn and I2/m , respectively. Such a structural difference will be of great importance to a complete understanding of the physical properties. {copyright} {ital 1998} {ital The American Physical Society}
