Purely inorganic open‐framework compounds (NH 4 ) 4 In 12 Se 20 ( 1 ) and (NH 4 ) 2 In 12 Se 19 ( 2 ) have been synthesized and their ion‐exchange properties are reported by M. Kanatzidis et al. in their Full Paper on page 51ff. The chalcogenide framework has innate reactivity towards soft heavy‐metal ions (Hg 2+ , Pb 2+ , Ag + ) and its pores are well suited for their capture. The authors show that 1 can effectively and selectively remove such metal ions from water.
