Date of deprecation: 12:58, Oct 22, 2013
Reason for deprecation: Deprecate record: there are no supporting data sources.

If you believe this record was deprecated in error, please use the Comment on this record button to contact the ChemSpider team.

Common reasons for deprecation are:
  • Chemically impossible structures (eg. incorrect valence atoms)
  • Lack of any linking data sources
  • Poor depiction of a structure that is already in ChemSpider
