Chlorine perchlorate
Chlorine perchlorate is a chemical compound with the formula . This chlorine oxide is an asymmetric oxide, with one chlorine atom in +1 oxidation state and the other +7, with proper formula . It is produced by the photodimerization of chlorine dioxide () at room temperature by 436 nm ultraviolet light:
:
Chlorine perchlorate can also be made by the following reaction at −45 °C.
:
Properties
Chlorine perchlorate is a pale greenish liquid. It is less stable than (chlorine dioxide) and decomposes at room temperature to give (oxygen), (chlorine) and (dichlorine hexoxide):
:
Chlorine perchlorate reacts with metal chlorides to form chlorine and the corresponding anhydrous perchlorate:
:
