    Description / Table of Contents: Synthese und IR-Untersuchungen von Methylgallium(III) und Gallium(III) Komplexen mit dreizähnigen LigandenMehrere neue 1:1 Komplexverbindungen, neutral bzw. anionisch, von Methylgallium(III) und Gallium(III) mit dreizähnigen Liganden (H2L; mit ONO und SNO) sowie ein Glycylglycin-Derivat werden dargestellt und ihre IR-Spektren in festem Zustand untersucht. Eine mögliche Anordnung der Liganden um das zentrale Atom in trigonal-bipyramidaler Form wird vorgeschlagen und diskutiert; so z. B. in den komplexen Anionen [Cl2GaL]- sowie in CH3GaL- und ClGaL-Verbindungen; in den letzteren in dimeren Anordnungen mit dreifach koordinierten Sauerstoffbrücken.
    Notes: Several new 1:1 complexes, neutral or anionic, formed by Methylgallium(III) and Gallium(III) with tridentate ligands (H2L; ONO and SNO donor atoms), as well as a glycylglycine derivative, have been synthesized, and characterized in the solid state by infrared spectroscopy. Data have been interpreted in terms of trigonal bipyramidal type configurations of the environment of the metal centre, in the complex anions [Cl2GaL]- as well as in compounds CH3GaL and ClGaL: in the latter two, dimerization would occur through bridging, three-coordinating oxygen atoms.
