Abstrakt: Direct oxidation of iron and copper in a donor-acceptor medium, L + CCl, where L is dimethylsulphoxide, dimethylformamide or acetonitrile was employed to obtain complex compounds: cis-[FeCl(DMSO)]Cl] ( 3), 2 FeCl · 3 DMSO ( 5), [FeCl(DMSO)][FeCl]] ( 6), [FeCl(DMSO)][FeClO] ( 7), cis-[FeCl(DMF)][FeCl] ( 8), [Fe(MeCN)][FeCl] ( 9) and cis-[CuCl(DMF)] ( 10), The structures of complexes ( 9) and ( 10) have been established by x-ray diffraction analysis and compared with those of ( 3), ( 6), ( 7) and ( 8) which are reported elsewhere. The [FeCl(DMSO)][FeClO] complex ( 7) is formed by oxidation of iron from cis-[FeCl(DMSO)][FeCl] ( 4) in ethanol. One of the 5 DMSO molecules of ( 7) was found to be disordered; the Mössbauer spectroscopy data suggest that it can move within the cation coordination sphere. Mössbauer spectroscopy and x-ray diffraction analysis indicate electron isomerism in one of the complexes. [ABSTRACT FROM AUTHOR]
