Abstract

Three new Pd(II) complexes of Schiff base ligands, namely, [Pd4(L1)4] (1), [Pd2(L2)2Cl2] (2) and [Pd(L3)2Cl2] (3) [HL1 = N-(benzylidene)-2-aminophenol; L2 = N-(2,4-dichlorobenzylidene)-2,6-diethylbenzenamine, L3 = 4-(2,4-dichlorobenzylide-neamino)phenol] have been synthesized using solvothermal methods and characterized by elemental analysis, spectroscopy and single crystal X-ray diffraction. The crystal structures of the free ligands were also determined. The μ-oxygen-bridged tetranuclear cyclometallated Pd(II) complex (1) contains four nearly planar units, in which PdII is four-coordinate. Complex 2 is a μ-chloro-bridged dinuclear cyclometallated Pd(II) complex, whereas complex 3 is mononuclear. The Heck reactions of bromobenzene with acrylic acid catalyzed by complexes 13 have also been studied.
