Abstract

The processes which take place in freshly precipitated insoluble metal nitroprussides, M[Fe(CN) 5 NO]· xH 2 O (M = Mn 2+ , Fe 2+ , Co 2+ , Ni 2+ , Cu 2+ , Zn 2+ and Cd 2+ ), their crystalline phases and their aged products have been studied by X-ray diffraction, Mossbauer, IR and thermogravimetric techniques. The processes entail a loss of zeolitic water. The stable phases are orthorhombic (Pnma) dihydrates (Mn 2+ , Fe 2+ , Cu 2+ , Cd 2+ and Zn 2+ ) and face-centred cubic (Fm3̄m) tetrahydrates for Co 2+ and Ni 2+ .
