to get this template --> Palladium(II) chloride, also known as '''palladium dichloride''', is a common starting material in Palladium chemistry. PREPARATION By reaction of the elements. STRUCTURE Two forms of PdCl2 are known. In both forms, the palladium centres adopt the square-planar coordination geometry that is characteristic of Pd(II). Furthermore, in both forms, the Pd(II) centres are linked by μ2-chloride bridges. The α-form of PdCl2 is a polymer, consisting of "infinite" slabs or chains. The β-form of PdCl2 is molecular, consisting of an octahedron of six Pd atoms. Each of the twelve edged of this octahedron is spanned by Cl-. PtCl2 adopts similar structures, whereas NiCl2 adopts the CdCl2 motif, featuring hexacoordinated Ni(II). USES Starting point in the synthesis of other palladium compounds. Palladium(II) chloride is not particularly soluble in water or non-coordinating solvents, and the first step is often to prepare the Acetonitrile or Benzonitrile complex. :PdCl2 + 2MeCN → {Link without Title} Palladium(II) chloride is sometimes used in carbon monoxide detectors. SAFETY Palladium compounds are not widely used industrially, and few studies are available concerning their hazards. However, the related Nickel and Platinum compounds are known to be Irritant s of the skin and the respiratory system and, in some cases, Carcinogen ic, and its is generally accepted as prudent to assume that palladium compounds share these risks.
