    Description / Table of Contents: Transition Metal Chalkogen Compounds. Preparation, Electronic and Vibrational Spectra of Diphenyldiselenophosphinato ComplexesThe anion of the diphenyldiselenophosphinic acid (dpspi) as a bidentate ligand forms complexes of the type [(C6H5)2PSe2]nM (M=metal). This ligand and its complexes with CoII, NiII, CuI, CdII, and ZnII are reported for the first time. The ligand field splitting parameters are calculated from the electronic spectra of Ni(dpspi)2 and Co(dpspi)2. The position of dpspi in the spectrochemical series is discussed. Its nephelauxetic effect is extremely high. The PSe stretching vibrations of the diphenyldiselenophosphinato complexes are assigned.
    Notes: Das Anion der Diphenyldiselenophosphinsäure („dpspi“) bildet als zweizähniger Ligand Komplexe des Typs [(C6H5)2PSe2]nM (M=Metall). Über diesen Liganden sowie die entsprechenden Komplexe mit CoII, NiII, CuI, CdII und ZnII wird in dieser Arbeit erstmalig berichtet. Aus den Elektronenspektren von Ni(dpspi)2 und Co(dpspi)2 werden die Ligandenfeldparameter berechnet. Die Einordnung von dpspi in die spektrochemische Reihe wird diskutiert. Der nephelauxetische Effekt ist außerordentlich groß. Die PSe-Valenzschwingungen der Diphenyldiselenophosphinato-Komplexe werden zugeordnet.
