Classical constant-pressure molecular dynamics calculations have been used to help rationalize the observed properties of both pure C[sub 60] and alkali-metal-doped fullerites K[sub x]C[sub 60]. An intermolecular potential based on atom-atom interactions and complete charge transfer from K to C[sub 60] yields lattice constants for C[sub 60] and K[sub 6]C[sub 60] in excellent agreement with experiment. The nature of the structural change that accompanies the alkali-metal-doping is discussed.
