A series of compounds of the type M<SUB>3</SUB>[Fe(CN)<SUB>5</SUB>CO]<SUB>2</SUB>·<I>x</I>H<SUB>2</SUB>O (M=Mn, Co, Ni, Cu, and Zn) have been studied by means of the X-ray diffraction powder patterns, magnetic measurements, infrared, electronic, and M\ddotossbauer spectra. Three compounds M<SUB>3</SUB>[Fe(CN)<SUB>5</SUB>CO]<SUB>2</SUB>·<I>x</I>H<SUB>2</SUB>O (M=Mn, Co, and Ni) crystallize in the face-centered cubic system. Copper compound Cu<SUB>3</SUB>[Fe(CN)<SUB>5</SUB>CO]<SUB>2</SUB>·18.5H<SUB>2</SUB>O belongs to the tetragonal system, zinc compound Zn<SUB>3</SUB>[Fe(CN)<SUB>5</SUB>CO]<SUB>2</SUB>·13.5H<SUB>2</SUB>O being amorphous. The structure of these compounds is described as a three-dimensional framework of two octahedral coordination units FeC<SUB>6</SUB> in the low spin state and MN<SUB>10⁄3</SUB>O<SUB>8⁄3</SUB> in the high spin state. The back donation in the Fe(CN)<SUB>5</SUB>CO<SUP>3−</SUP> moiety is enhanced by the bridge formation through CN<SUP>−</SUP> and CO ligands, <I>i.e.</I> upon the formation of M<SUB>3</SUB>[Fe(CN)<SUB>5</SUB>CO]<SUB>2</SUB>·<I>x</I>H<SUB>2</SUB>O from the corresponding sodium salt.
