Abstract :
Single crystals of the 2D polymerized tetragonal phase of C60 without orientational domains were obtained under high pressure and high temperature. The crystal structure of this phase was resolved using single crystal X-ray diffraction data. The cell parameters are a=9.064(3) and c=15.039(8) إ with the space group P42/mmc and Z=2. A structural model of this phase proposed early was confirmed and refined to final R=0.075. The structure is slightly disordered. It consists of a random combination of the P42/mmc layers (84%) and of the Immm layers (16%), along the c-axis.
