Synthesis and Crystal Structure of Dichlorodianiline Palladium （Ⅱ） （C6H5NH2）2PdCl2

1 INTRODUCTION Palladium compounds have attracted much attention as a consequence of their application in homogeneous and heterogeneous catalyses[1]. For instance, palladium compounds are the most active catalysts for the carbonylation, such as palladium-catalyzed carbonylation of nitroarenes, aryl halides, alkyne and so on[2～4]. Some dramatic results in the homogeneous catalysis of the reactions of organic compounds, particularly the successful commercial exploitation of the Wacker on…

Synthesis and Crystal structure of cis—Dichloro—（tetrakis（methylthio）—ethylene）Palladium（Ⅱ）

1 INTRODUCTION Recently much more attention has been paid to palladium bidentate chelate. Such as palladium diphosphino complexes can be used to catalyze crossing-coupling[1] and monocoupling[2]; palladium diamine complexes can be used to catalyze norbornene polymerization[3] and it can also bind to biologically important molecules[4]. Owing to the above reasons, palladium(Ⅱ) complexes with these ligainds are well researched. However, the neutral analogs with derivatives of dithiole are…

Syntheses and Crystal Structures of Three Palladium（Ⅱ） Complexes with Isonitrosobenzoylacetoneimine Ligand

Three palladium (II) complexes with the isonitrosobenzoylacetoneimine (HIBI) ligand, Pd (p‐CH₃C₆H₄IBI)₂ (1), Pd (C₆H₅IBI)₂ (2) and Pd₂Cl₂ (C₆H₅CH₂IBI)₂ · CHCl₃ (3), were prepared and characterized by IR, Raman and X‐ray diffraction studies. The geometries around the palladium atoms in the complexes 1 and 2 are distorted trans‐PdN₄ square planes, and the Schiff base ligands RIBI^? are coordinated through their oximo‐nitrogen atoms and imino‐nitrogen atoms. The week Pd…H? C agostic interactions [Pd…H = 0.2764 nm] complete the hexacoordinate environment around palladium in the complex 1. The octahedral deformation of the classical square planar environment of the Pd atom is due to the week Pd…O (1b) interactions [Pd? O (1b) = 0.3157 (9) nm] in the complex 2. The complex 3 is a first example of binuclear complex with isonitrosoketoimine ligands, in which one of oximo groups is coordinated through oximo‐nitrogen and oximo‐oxygen atoms.
