Abstract
The preparation and properties of the ferricyanides of Cd++, Mn++, Zn++, Co++, Cu++ and Ni++ are described. Results of an X ray analysis confirm the skeleton, found by Keggin and Miles in the case of other regular complex cyanides. The position of C and N on the cell edges could be stated more precisely. The distribution of metal ions and water within the skeleton results in an averaged structure with kation positions on the octant diagonals, in the neighbourhood of the Fe corners. It is argued, that in the “dry” crystal powder water remains enclosed between the crystal particles.Keywords
