Editing Chalcogen (section)

===Other===
Chalcogens form single bonds and double bonds with other [[carbon group]] elements than carbon, such as [[silicon]], [[germanium]], and [[tin]]. Such compounds typically form from a reaction of carbon group halides and chalcogenol salts or chalcogenol [[base (chemistry)|bases]]. Cyclic compounds with chalcogens, carbon group elements, and boron atoms exist, and occur from the reaction of boron dichalcogenates and carbon group metal halides. Compounds in the form of M-E, where M is silicon, germanium, or tin, and E is sulfur, selenium or tellurium have been discovered. These form when carbon group [[hydride]]s react or when heavier versions of [[carbene]]s react.{{dubious|date=September 2014}} Sulfur and tellurium can bond with organic compounds containing both silicon and phosphorus.<ref name="handbook"/>

All of the chalcogens form [[hydride]]s. In some cases this occurs with chalcogens bonding with two hydrogen atoms.<ref name="ReferenceB"/> However [[tellurium hydride]] and [[polonium hydride]] are both volatile and highly [[labile]].<ref name = "holleman">{{cite book|editor1=Holleman, Arnold F. |editor2=Wiber, Egon |editor3=Wiberg, Nils |url = https://books.google.com/books?id=Mtth5g59dEIC&pg=PA470|title = Inorganic Chemistry|pages=470 ff|isbn = 978-0-12-352651-9|year=2001|publisher=Academic Press }}</ref> Also, oxygen can bond to hydrogen in a 1:1 ratio as in [[hydrogen peroxide]], but this compound is unstable.<ref name="wisc"/>

Chalcogen compounds form a number of [[interchalcogen]]s. For instance, sulfur forms the toxic [[sulfur dioxide]] and [[sulfur trioxide]].<ref name="wisc"/> Tellurium also forms oxides. There are some chalcogen sulfides as well. These include [[selenium sulfide]], an ingredient in some [[shampoo]]s.<ref name="The Elements"/>

Since 1990, a number of [[boride]]s with chalcogens bonded to them have been detected. The chalcogens in these compounds are mostly sulfur, although some do contain selenium instead. One such chalcogen boride consists of two molecules of [[dimethyl sulfide]] attached to a boron-hydrogen molecule. Other important boron-chalcogen compounds include [[macropolyhedral]] systems. Such compounds tend to feature sulfur as the chalcogen. There are also chalcogen borides with two, three, or four chalcogens. Many of these contain sulfur but some, such as Na<sub>2</sub>B<sub>2</sub>Se<sub>7</sub> contain selenium instead.<ref>{{cite book|editor = Devillanova, Francesco A. |title=Handbook of chalcogen chemistry|url=https://books.google.com/books?id=IvGnUAaSqOsC|year = 2007|publisher=Royal Society of Chemistry |isbn = 978-0-85404-366-8 |access-date=November 25, 2013}}</ref>
