Complexes of Np(V)-Cr(III) and Np(V)-Rh(III) were prepared, and the complexes were separated from the uncomplexed ions by ion exchange. The Mossbauer spectral study of these complexes is reported. A structure has been suggested for the complexes that involves substitution of the NpO/sub 2//sup +/ ion for a water molecule in the first coordination sphere of the hexaaquochromium(III) and of the hexaaquorhodium(III) ion. The magnetic splitting in the spectra of the Np(V)-Cr(III) complex and the lack of magnetic splitting for the major fraction of the Np(V)-Rh(III) complex are consistent with the suggested structure.
