Heterobimetallic Chalcogenidometallate Strands: Synthesis, Structure, Magnetism, and Conductivity

Two salts with one-dimensional, SiS2-type telluridostannate chain anions {[MSnTe4]2−}n, Rb2[HgSnTe4] (2) and (NMe4)2[MnSnTe4] (3), were prepared by the reactions of [SnTe]4− anions with Hg2+ or Mn2+ ions in solution. We present the crystal structures of 2 and 3, as well as the magnetic properties of the previously reported Cs+ analogue Cs2[MnSnTe4] (1)
