Abstract

original image

Die Wahrheit enthüllt: Das Dimer [{(μ2-PNP)Co}2] enthält einen rautenförmigen Co2N2-Kern und verbrückende PNP-Liganden (Bild: Co hellblau, N dunkelblau, P grün, C grau, nur ein C-Atom der Isopropylgruppen ist gezeigt; PNP=[N{2-P(CHMe2)2-4-MeC6H3}2]). Bei der Reaktion mit ClCPh3, CO oder N2 werden die PNP-Liganden zu terminal chelatisierenden Liganden, wobei vierfach koordinierte Co-Komplexe wie [{(PNP)Co}22-N2)] entstehen.
