摘要：

The room temperature structure of the hexagonal family of modifications of pure C70 has been studied by single-crystal X-ray diffraction. The experimental evidence indicates rotational symmetry of the molecular electron density and supports the previously published assumptions that the molecules are freely rotating tops arranged in a hexagonal close packing, space group P6(3)/mmc. The tops librate about axes perpendicular to the rotation axis with a r.m.s. amplitude of 7.33(3)degrees. The distances between the atomic planes perpendicular to the molecular axis agree well with earlier work.
