Abstract: | Information on physical and chemical properties, especially on the structure and chemical bonding of M[FeCl4]-complexes has been obtained by measurements of the optical absorption, the MÖSSBAUER effect and EPR. (M stands for a monovalent cation.) The iron(III) chlorocomplex compounds Ag[FeCl4], Rb[FeCl4] and Li[FeCl4] have been proved to exist within the systems MCl? FeCl3 by measurements of optical spectra and EPR. |
