Orange Book Entry
This is an ion containing an unpaired electron, which is thus both an ion and a radical. In mass spectroscopy an unpaired electron is denoted by a superscript dot alongside the superscript symbol for charge, thus C2H6+????????????????????? or SF6 -?????????????????????. An alternative form (IUPAC Compendium of Chemical Terminology, 1987) used in inorganic and organic chemistry literature uses the symbolism as in X?????????????????????+. For species with more than one charge and/or more than one unpaired electron the styles X(2+) (2?????????????????????) or X(2?????????????????????) (2+) are recommended.
