Abstract

The crystal structures of two manganese hexacyanometallates(II), Mn₂[Fe(CN)₆].8H₂O and Mn₂[Os(CN)₆].8H₂O, were refined from X-ray powder diffraction data using the Rietveld method, with the reported structure for Mn₂[Ru(CN)₆].8H₂O used as a structural model. These compounds are isomorphous and crystallize in the monoclinic space group P2₁/n. Their crystallization water is not firmly bound and can be removed without disrupting the M-C≡N-Mn network. In the dehydrated complexes, the outer cation (Mn) remains linked to only three N atoms from Cn ligands while the inner cation (Fe,Os) preserves its coordination sphere. The IR, Raman, and Mössbauer spectra for the hydrated and anhydrous forms are explained based on the refined structures.
