Abstract	Cs4C60 is reported as a pure phase for the first time, using low-temperature synthesis. It adopts an orthorhombic distortion of the body-centred tetragonal (bct) A4C60 structure found for K4C60 and Rb4C60 , due to the orientational ordering of the C604– anions with the 6:6 bonds directed along the orthorhombic b-axis. The caesium cations occupy two distinct distorted tetrahedral sites, producing the orientational order to avoid close contact with the five-membered rings of neighbouring C604– anions. The structure-directing influence of large cations on fulleride structures and the implications for Jahn–Teller distortions of the fulleride anions are discussed.
