PtCl4

PtCl4, also known as platinum(IV) chloride, is a chemical compound consisting of platinum and chlorine. It is a yellow crystalline solid at room temperature. The compound is formed when platinum is exposed to chlorine gas, resulting in the oxidation of platinum from its +2 state to the +4 state. PtCl4 is highly reactive and can undergo hydrolysis in the presence of water, forming various platinum oxychloride complexes.

The compound has a square planar geometry around the platinum atom, with four chlorine atoms arranged at the vertices of a square. This geometry is characteristic of compounds with a d8 electron configuration, such as PtCl4. The compound is soluble in polar solvents like water and ethanol, but insoluble in non-polar solvents like benzene.

PtCl4 is used in various chemical reactions as a source of platinum(IV) ions. It is also used in the synthesis of other platinum compounds and as a catalyst in organic synthesis. The compound is toxic and should be handled with care, using appropriate personal protective equipment.
