mononuclear [NiL2] (6). X-Ray crystallography revealed that the κ2-benzamidinate ligand L− is bonded to the metal centre of these complexes in an unsymmetrical fashion. The TMEDA ligand in 2–5 exhibits different coordination modes. It acts as a chelating ligand in 3, as a monodentate ligand in 4, and as an unusual N,N′-bridging ligand in 2 and 5.
