Heteroleptic nickel pentacoordinate complexes with the macrocyclic ligands 2,4,4-trimethyl-1,5,9-triazacyclododec-1-ene (Me3-mcN3) or its 9-methyl derivative (Me4-mcN3), as ancillary ligands, and O,O′-(diphenylphosphineoxide)amidate ligands, [RC(O)NP(O)Ph2]? (R = C6H6 (1), C5H4N (2), C4H3S (3)), have been prepared as well as related acetylacetonate derivatives. The complexes have been studied by spectroscopic methods (IR, UV-Vis and 1H NMR). In acetone solution, the complexes exhibit isotropically shifted 1H NMR resonances. The full assignment of these resonances has been achieved using one- and two-dimensional 1H NMR techniques. The single-crystal structures of {(Me4-mcN3)Ni[OP(Ph2)NC(Tf)O]}[PF6] (9) and {(Me3-mcN3)Ni(acac)}[PF6] (10) have been established by X-ray diffraction.
