We report x-ray powder diffraction studies on RbxC60 and KxC60. It is shown that at room temperature there exist stoichiometric compounds in the RbxC60 and KxC60 systems at the x = 1 composition. Their equilibrium structures are pseudo body centered orthorhombic. The C60-C60 intermolecular separation (9.1 angstrom) is the shortest among the known alkali-fullerides. A first order phase transition is observed at about 380 K from the high temperature fcc phase to the room temperature orthorhombic phase.
