Abstract

A new family of di-, tri- and tetra-nuclear Ni(II) complexes containing oxalic amidinates as bridging ligands is described in which both peripheral Ni centres are catalytically active in the oligomerization or polymerization of ethylene or in the selective cross coupling of Ar–X with Ar′–MgX.
