Platinum Chloride
Platinum chloride may refer to: * Platinum(II) chloride * Platinum(IV) chloride Platinum(IV) chloride is the inorganic compound of platinum and chlorine with the empirical formula PtCl4. This brown solid features platinum in the 4+ oxidation state. Structure Typical of Pt(IV), the metal centers adopt an octahedral coordinati ... {{Short pages monitor ...

Platinum(II) Chloride
Platinum(II) chloride is the chemical compound Pt Cl2. It is an important precursor used in the preparation of other platinum compounds. It exists in two crystalline forms, but the main properties are somewhat similar: dark brown, insoluble in water, diamagnetic, and odorless. Structure The structures of PtCl2 and PdCl2 are similar. These dichlorides exist in both polymeric, or "α", and hexameric, or "β" structures. The β form converts to the α form at 500 °C. In the β form, the Pt-Pt distances are 3.32–3.40 Å, indicative of some bonding between the pairs of metals. In both forms of PtCl2, each Pt center is four-coordinate, being surrounded by four chloride ligands. Complementarily, each Cl center is two-coordinate, being connected to two platinum atoms. The structure of α-PtCl2 is reported to be disordered and contain edge- and/or corner-sharing square-planar PtCl4 units. Preparation β-PtCl2 is prepared by heating chloroplatinic acid to 350 °C in ai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
