Coordination Studies of a New Unsymmetrical κ4-PNN‘N‘ ‘-Tetradentate Ligand: Stepwise Formation and Structural Characterization

“…There has been increasing interest in the development of new tetradentate ligands, including tetradentate π-radical ligands, with two (or more) different donor centers for their versatile coordination behavior, , radioimaging/radiotherapeutic uses, − liquid crystalline, magnetic and phosphorescent properties, and numerous applications in catalysis (including asymmetric synthesis). − The most popular donor set combinations are those comprising N 2 O 2 7,9,21 and P 2 N 2 3,12,15,18,22 atoms although, more recently, examples based on N 2 S 2 16,23 have been described. Ourselves and others − have been interested in terdentate tertiary phosphines of the general type PNX (X = N, P, O, S, or Se donor center). We recently described a new Schiff base ligand and its coordination chemistry with a PNSe donor set combination …”

Synthesis and characterization of nickel and palladium complexes containing hetero-multidentate PNO ligands

“…Ligand L A was studied for the coordination toward Fe(III), Co(III) and Re(V) ions [5], whereas ligand L B demonstrated the versatility in the formation of Ni(II) [6a], Pd(II) [4,6], Pt(II) [6], and Ru(II) [7] complexes as a tridentate. The binuclear Rh(I) complexes of ligand L C were studied for hydrosilylation of ketones [8]. In our laboratory, the coordination behavior of ligand L D toward palladium(II) was investigated [9,10].…”
