Salt metathesis reactions between ethylenediamine (en) solutions of the K(3)E(7) (E = P, As) Zintl phases and post-transition metal halides (InCl(3), TlCl, SnI(2) and PbI(2)) have yielded a family of novel heteroatomic cluster anions, [In(E(7))(2)](3-), [TlE(7)](2-) and [E'E(15)](3-) (E' = Sn, Pb; E = P, As). Several of these new species have been characterized by single-crystal X-ray diffraction as salts of sequestered potassium cations in [K(2,2,2-crypt)](3)[In(P(7))(2)]·3.5py (1), [K(2,2,2...Expand abstract
