| Abstract: Two series of polymers based on iron complexes of the tetrathiafulvalenetetrathiolate (ttftt4-) of the stoichiometry [(Fe-ttftt)Mx]n(M=Co,Ni,Cu,Hg; x =1.2,0.5,0.7,0.9) and [(Fe-ttftt)Lny]n (Ln=Nd, y = 0.3; Ln=Sm,Eu,Tb, y =0.4) are prepared in absolute ethanol. These insoluble amorphous polymeric complexes have been characterized by elemental analysis, IRspectra, TG-DTA techniques, Mössbauer spectroscopy and conductivity measurements. The spectroscopicresults are discussed in relation to the structure of these compounds. In the Mössbauer spectra of the investigated complexes, the isomer shift shows trivalent iron ions as the main component in the samples, and the quadrupole splitting is typical for distorted octahedral coordination geometry. The complexes behave as semiconductors at 25℃ as compacted pellets. |
