This section lists some binary compounds with halogens (known as halides), oxygen (known as oxides), hydrogen (known as hydrides), and some other compounds of ruthenium. For each compound, a formal oxidation number for ruthenium is given, but the usefulness of this number is limited forp-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 ruthenium (where known), the most common oxidation numbers of ruthenium are:4, and 3.

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.
