Abstract

We report the synthesis and characterization of the inorganic heterocyclic complexes In(OPPh 2NPPh 2O)3 and In(SPPh 2NPPh 2S)3. The structure of the sulfur derivative was determined by X-ray methods. The complex presents a distorted Oh symmetry and it is compared with the Bi(III) analog. The31P-NMR data and the X-ray structural determination suggest that the bulky ligands are responsible for the geometrical features in these complexes and therefore, for the Bi(III) analogs perhaps the lone pair does not play an important role in the structure.

Zusammenfassung

Es wird über die Synthese und Charakterisierung der anorganischen heterocyclischen Komplexe In(OPPh 2NPPh 2O)3 und In(SPPh 2NPPh 2S)3 berichtet. Die Struktur des Schwefelderivates wurde mit röntgenographischen Methoden bestimmt. Der Komplex gehört einer verdrillten Oh Symmetrie an und wird mit dem Bi(II)-Analog verglichen. Die31P-NMR-Daten und die Röntgenstruktur legen nahe, daß die raumbeanspruchenden Liganden für die Geometrie dieser Komplexe verantwortlich sind und daher bei der Struktur des Bi(II)-Analogen die freien Elektronenpaare eine untergeordnete Rolle spielen.
