Platinum - ₇₈Pt: compounds information

This section lists some binary compounds with halogens (known as halides), oxygen (known as oxides), hydrogen (known as hydrides), and some other compounds of platinum. For each compound, a formal oxidation number for platinum is given, but the usefulness of this number is limited for p-block elements in particular. Based upon that oxidation number, an electronic configuration is also given but note that for more exotic compounds you should view this as a guide only.

In compounds of platinum (where known), the most common oxidation numbers of platinum are: 4, and 2.

Hydrides

The term hydride is used to indicate compounds of the type M_xH_y and not necessarily to indicate that any compounds listed behave as hydrides chemically.
