    Description / Table of Contents: Nickel(0) Complexes with the Donor Set N2P2Mixed ligand complexes of the type (dipy)Ni(PR3)2 are stabil, provided the n-donor α,α′ -dipyridyl is combined with a tertiary phosphine or a phosphite acting as a π-acceptor. They may be prepared from (R3P)2Ni(C2H4) and dipy, from (dipy) Ni(COD) and PR3, or from (dipy) Ni(C2H5)2 and PR3. Starting with [(C6H11)3P]2Ni(C2H4) or (dipy)Ni(COD) the synthesis of the complex (dipy)Ni[P(C6H11)3]2 containing only n-donor ligands, failed. By the reaction of (dipy)Ni(C2H5)2 with (C6H11)3P the olefin complex [(C6H11)3P]2Ni(C2H4) was formed.
    Notes: Gemischtliganden-Komplexe des Typs (dipy)Ni(PR3)2 sind dann stabil, wenn dem n-Donator α,α′-Dipyridyl ein Phosphan bzw. Phosphit mit π-Akzeptorfunktion als Zweitligand gegenübersteht. Sie können aus (R3P)2Ni(C2H4) und dipy, aus (dipy) Ni(COD) und PR3 oder aus (dipy)Ni(C2H5)2 und PR3 dargestellt werden.Die Synthese des Komplexes (dipy)Ni[P(C6H11)3]2, in dem nur n-Donatoren als Liganden vorlägen, gelang, wenn von [(C6H11)3P]2Ni(C2H4) oder (dipy)Ni(COD) ausgegangen wurde, nicht. Die Reaktion von (dipy) Ni(C2H5)2 mit (C6H11)3P führt zu [(C6H11)3P]2Ni(C2H4).
