A PALLADIUM(II) COMPLEX OF A TETRADENTATE AMINE PHENOL LIGAND

A palladium(II) complex of an amine-phenol ligand N,N'-bis(2-hydroxybe nzyl)1,4-diaminobutane has been synthesized and characterized by NMR, IR, and X-ray diffraction studies. Diffraction data were collected wit h a Nonius CAD-4 diffractometer with theta-2theta scan and Mo Kalpha r adiation. The structure was solved by conventional methods resulting i n an R factor of 0.022 for 1058 independent reflections. The X-ray str ucture shows a discrete mononuclear square planar complex in which the Pd is coordinated to the two nitrogens and two oxygens of the ligand. The complex is neutral with the Pd(II) charge balanced by deprotonati on of both phenolic oxygens.
