Abstract
Polycatenar saturated macrocycles yl]-1,10-diaza-4,7,13,16-tetrathiacy clo-octadecane (3b) and yl]-1,10-diaza-4,7,13,16-tetrathiacyclo-octade cane (3d) reacted with [Pd(MeCN)(4)][BF4](2) led to the cationic compl exes [4b][BF4](2) and [4d][BF4](2), respectively. Complexes [4b][BF4]( 2) and [4d][BF4](2) showed smectic mesomorphism on heating as confirme d by small angle X-ray diffraction. A concurrent, irreversible structu ral change of the complex cations was observed and a tentative explana tion is suggested.
