This paper describes the combustion properties of the amino‐substituted guanidinium 4,4′,5,5′‐tetranitro‐2,2′‐biimidazolate (N4BIM) series, including the bis‐mono, di and triaminoguanidinium salts. These salts are of interest as propellant ingredient additives, and in particular, the bis‐triaminoguanidinium salt of N4BIM displays excellent burn rate and combustion behavior. Our combustion studies have shown that TAGN4‐BIM displays a fast burning rate and has the lowest pressure dependence exponent yet measured for a triaminoguanidinium salt.
