Descripción :	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–CwN–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 Mo¨ssbauer spectra for the hydrated and anhydrous forms are explained based on the refined structures. © 2002 International Centre for Diffraction Data. @DOI: 10.1154/1.1469023#
