ABSTRACT
Abstract. The encapsulation of the simple binary compound Lal3 within the inner cylindrical bore of a single-walled carbon nanotube (SWNT) yielded an unprecedented structure of Lah. The filling material was encapsulated within SWNTs by heating bulk Lal3 in vacuo in the presence of SWNTs. The obtained encapsulation composite was analysed using energy-dispersive X-ray microanalysis (EDX) and focal series restoration approaches of highresolution transmission electron microscopy (HRTEM) images, to reveal a one-dimensional La12 fragment, 'crystallising' in the structure of Lal3 with 1/3 of the iodine positions unoccupied, whilst simultaneously identifying the chirality of the surrounding SWNT.
