Abstract

original image

Dunkelblaue Kristalle eines homoleptischen Palladiumkomplexes mit zwei Phosphanylradikal-Liganden wurden nach einer einfachen Ligandenaustauschreaktion erhalten. π-Wechselwirkungen zwischen Pd-Orbitalen und den SOMOs der Phosphanylradikale erklären den diamagnetischen Charakter, die intensiv blaue Farbe und die kleinen P-Pd-Abstände. Eine Hydrierung ergab den entsprechenden Bis(dialkylhydrophosphan)palladium-Komplex.
