    • The IUPAC name for the 5-nitrogen core is diaminomethylidene guanidine, and some authors refer to it as biguanide. To avoid confusion with guanidine or biguanide, we describe it as pentanidine (for the base) or pentanidium (for the salt). There are a few examples of this structure in the literature.
