By means of specimen shifting and zero-loss energy filtering using an energy-filtering transmission electron microscope, main amorphous halos with the centre corresponding to 0.7 nm are recorded from thin films of a polysioxane bound UO22
-complex as well as a polysioxane-bound Eu3
-complex at room temperature. Furthermore, electron diffraction patterns measured at low temperatures around 100 K show that the thin film of polysiloxane bound UO22
-complex becomes polycrystalline. These results show some analogy to the results of X-ray investigation [Andeianov K A et al. (1972) J. Polymer Sci. Part Al 10: 122] of the linear polydimethylsiloxane without binding metal-complex.
