(NH(4))Mg(HSO(4))(SO(4))(H(2)O)(2) and NaSc(CrO(4))(2)(H(2)O)(2), two crystal structures com­prising kröhnkite-type chains, and the temperature-induced phase transition (NH(4))Mg(HSO(4))(SO(4))(H(2)O)(2) [Image: see text] (NH(4))MgH(SO(4))(2)(H(2)O)(2)

The crystal structure of the mineral kröhnkite, Na(2)Cu(SO(4))(2)(H(2)O)(2), contains infinite chains com­posed of [CuO(4)(OH(2))(2)] octa­hedra corner-linked with SO(4) tetra­hedra. Such or similar tetra­hedral–octa­hedral ‘kröhnkite-type’ chains are present in the crystal structures of numerous co...
