Chemistry:Oxyarsenides

From HandWiki
Short description: Class of chemical compounds

Oxyarsenides or arsenide oxides are chemical compounds formally containing the group AsO, with one arsenic and one oxygen atom. The arsenic and oxygen are not bound together as in arsenates or arsenites, instead they make a separate presence bound to the cations (metals), and could be considered as a mixed arsenide-oxide compound. So a compound with OmAsn requires cations to balance a negative charge of 2m+3n. The cations will have charges of +2 or +3. The trications are often rare earth elements or actinides. They are in the category of oxypnictide compounds.

Some of these compounds are superconductors, but may require doping with fluoride or oxygen deficiency.[1] Yet others undergo colossal magnetoresistance with a lowered electrical resistance in a magnetic field.

Many compounds are layered, containing two metals with the formula XZAsO, with an XAs layer alternating with a ZO layer.
