properties

Potassium tetrachloridoplatinate

Potassium tetrachloridoplatinate is a red, odorless solid that is sparingly soluble in water. It has a tetragonal crystal structure with the space group P 4 / mmm (space group no. 123) and the lattice parameters a = 699 pm and c = 413 pm. The ammine complexes, [Pt (NH ₃ ) ₄ ] [PtCl ₄ ] and [Pt (NH ₃ ) ₄ ] Cl ₂ are formed with ammonia solution . Template: room group / 123

use

Potassium tetrachloridoplatinate is used for the production of metal bis (dithiolates), which are used, for example, in laser technology and optics. It is also used to produce colloidal platinum nanoparticles for catalysis and photocatalysts.
