ligand is slightly puckered (Figure and Table ). The bond lengths and torsion angle of DIA are comparable in magnitude with the respective homoleptic analogues (Ni(h 3 -allyl)2 and Ni(DIA)2, Table and). The central carbons of the two ligands are oriented syn to each other, whereas in the homoleptic complexes, the two ligands are anti. The iso-propyl groups of the amidinate ligand in 1-Ni are facing towards the metal center whereas in Ni(DIA)2 they are alternatingly facing in and out, to minimize steric interactions.
