摘要

A structural model of the nanocomposite consisting of one-dimensional (1D) α-SnF2 single crystals and single-wall carbon nanotubes (SWCNTs) is proposed. The main cationic motif is revealed in the structure of monoclinic modification: two-layer packing of tin cations along the [283] direction. Four theo-retical structural projections of a 1D crystal on the plane parallel to the [283] direction are determined and described. A fragment of the α-SnF_2 structure in an SWCNT (with a channel diameter of 1.02 nm) is calculated. High-resolution electron microscopy (HREM) images are modeled. These images correspond to the actually observed HREM patterns.
