Summary:Results of synthesis of stoichiometric, superconducting K 3C 60 and Rb 3C 60 by precipitation from liquid ammonia are described. The material was studied by means of X-ray diffraction and magnetic susceptibility measurements. The superconducting phases reproduced from this synthesis, without recourse to high temperature anneal, have properties consistent with those of vapor doped materials. The observed magnetic properties are interpreted in terms of the grain size and the links between the grains.
