<p> The synthesis and X-ray crystallographic determination of solid derivatives of homo- and heteropolyatomic anions derived from Zintl phases has generally yielded the least soluble of the ions present in solution. Many other species present in these solutions have remained unidentified until recently when considerable effort directed towards the investigation of the solution chemistries of Zintl anions has been put forth.</p> <p> The present work is mainly concerned with the characterization of new Zintl anions in solution using multinuclear magnetic resonance spectroscopy as the primary investigative tool. These studies include (1) the tetrahedral SnCh4^4- (Ch = selenium and/or tellurium), (2) the dimer of SnSe3^2-, Sn2Se6^4-, (3) several interesting but, as-of-yet, unidentified species present in solutions derived from ternary Na/Sn/Te alloys and present in the reaction of Sn(II) Cl2 with Te2^2-, and (4) a set of possible multi-thallium-tellurium species. Relevant chemical shifts and nuclear spin-spin coupling constants are reported and trends discussed.</p> <p>119Sn Mössbauer investigations of all tin-containing species is also presented as is a brief discussion of the
