Abstract

original image

PNP schirmt Hydrid ab: Die Hydrogenolyse von Dialkylvorstufen ergibt die dreikernigen Hexahydridkomplexe A (Me-PNPiPr={4-Me-2-(iPr2P)C6H3}2N, Ln=Y, Lu), die durch Umsetzung mit [NEt3H][BPh4] in die ersten kationischen dreikernigen Polyhydride B übergehen. Auch kationische zweikernige Trihydridkomplexe C wurden erstmals erhalten (im Bild sind nur die zentralen Struktureinheiten gezeigt; Y grün, H türkis, O rot, C schwarz).
