ABSTRACT: A systematic crystallization study of {(NH4)[M(HSO4)(SO4)(H2O)2]} n com-pounds, catena-poly[ammonium [[di-aqua-metal(II)]-μ-(hydrogen sulfato)-μ-sul-fato]], revealed that crystals of the M = Fe, Co and Ni members could be grown by evaporation of mixed equimolar aqueous solutions of NH4HSO4 and the corresponding MSO4 sulfate, whereas for M = Mn, Cu, Zn different products were obtained under these conditions. The (NH4)M(HSO4)(SO4)(H2O)2 compounds (M = Fe, Co, Ni) show a similar behavior to the magnesium analogue, i.e. a reversible structural phase transition from an ordered tric
