✦ Synopsis

The crystal structure and defect structures of C6o material have been studied by means of X-ray diffraction, high-resolution electron microscopy and electron diffraction. The diffraction measurements show that the C60 crystal has the face-centered cubic (fcc) structure with lattice parameter a = 1.42 rim. High-resolution electron microscopy observations, combined with the analyses of selected area electron diffraction, indicate that the coherent twins situated in the { 111} planes frequently appear in the C6o crystal. The disordered stacking along the ( 111 ) direction and other kinds of defects appearing in the new material have also been investigated. Upon in situ cooling and heating from 130 K to 700 K, the structural stability of the C60 crystal has been observed.
