Cyanogen selenocyanate, with the chemical formula SeCN-CN, is a chemical compound that contains both selenocyanate (SeCN-) and cyanogen (CN) groups. It is an inorganic compound composed of selenium (Se), carbon (C), and nitrogen (N).

Preparation and Properties of Cyanogen Selenocyanate: Cyanogen selenocyanate can be prepared by the reaction of cyanogen chloride (CNCl) with sodium selenocyanate (NaSeCN):

CNCl + NaSeCN → SeCN-CN + NaCl

Cyanogen selenocyanate is a yellowish-white crystalline solid. However, there is limited information available about this compound as it is not commonly used or studied due to its hazardous nature and lack of practical applications.

Safety Considerations: Due to its complex structure and the presence of both cyanide and selenocyanate groups, cyanogen selenocyanate is expected to be highly toxic and potentially hazardous. Both cyanide and selenium compounds can pose severe health risks and should be handled with extreme caution.

As with all toxic and reactive substances, the use and handling of cyanogen selenocyanate require specialized training, protective equipment, and strict safety protocols. The compound is not commonly used or available for commercial or academic purposes due to its potential risks.

Since cyanogen selenocyanate is not well-documented and studied, it is essential to consult with experts in the field of chemical safety and industrial hygiene if you encounter this compound or need more specific information about its properties and safety considerations.
