    Description / Table of Contents: Infrarot- und MÖSSBAUER-spektroskopische Untersuchungen an Komplexen von Hal2SnIV mit dreizähnigen LigandenNeue Komplexverbindungen von Typ hal2Sntrid werden dargestellt (hal = Cl, Br, und trid2- = ebene, dreizähnige Liganden mit ONO- und SNO-Atomen, als zweiwertige Anionen). In festem Zustand wurden die Strukturen durch IR- und MÖSSBAUER-Spektren untersucht. Mögliche Anordnungen der Liganden um das Zinn(IV)-Atom werden vorgeschlagen und diskutiert.Wahrscheinlich sind alle diese Verbindungen monomer mit einer trigonal-bipyramidalen Struktur; aber es können polymere oder dimere Anordnungen mit O- oder Cl-Brücken, besonders bei Br2Sntrid, nicht völlig ausgeschlossen werden.
    Notes: Novel complexes hal2Sntrid, where hal = Cl, Br, and trid2- are dianions of „planar“ tridentate ligands with ONO and SNO donor basic atoms, were synthesized and structurally investigated in the solid state mainly by far infrared and MÖSSBAUER spectroscopy. Possible configurations were advanced and discussed, and it was concluded that the most probable is a monomeric trigonal bipyramidal structure for all compounds, although polymers, or dimers with O or Cl bridges, were not a priori excluded, in a special way for Br2Sntrid.
