Summary The preparations and thermal decompositions of platinum halides PtXn (X = 1, Br, Cl) have been reinvestigated. The tetrahalides consist characteristically of PtX6 octahedra linked into chains by two common edges, a structural group ing present in two of three modifications of PtI4 and in PtBr4 and PtCl4. Normal thermal decomposition of PtX4 does not give the PtX3 compounds, but these can be prepared by other methods. They are all diamagnetic and for X = Cl and Br consist of both Pt(II) and PC(IV) structural elements. All three Ptl4 modifications and PtI3 decompose to a new Pt3I8 phase and subsequently to PtI2 which is dimorphic. PtBr4, PtCl4, PtBr3 and PtCl3 decompose to the respective dihalides for which there is also evidence of polymorphism.
