Abstract

This invention relates to amino-substituted guanidine decahydrodecaborates,hich are shown to be novel boron-containing salts that have particular utility as high energy monopropellants. The invention includes the diamino-guanidinium and monoaminoguanidinium salts of decahydrodecaboric acid, and as preferred products of processes for preparing same.

Claims

1. The monoaminoguanidinium salt of decahydrodecaboric acid, having the formula (CNHNH₂ (NH₂)₂)₂ B₁₀ H₁₀.

2. The monoaminoguanidine salt of the decahydrodecaborate (-2) ion as represented by the structural formula:

##STR2## wherein resonance stabilization is achieved by protonating a free guanidine base to form the unipositive ion.

3. The diaminoguanidine salt of decahydrodecaboric acid, having the formula (C(NHNH₂)₂ NH₂)₂ B₁₀ H₁₀.

4. The diaminoguanidine salt of the decahydrodecaborate (-2) ion as represented by the structural formula:

##STR3## wherein resonance stabilization is achieved by protonating a free substituted guanidine base to form the unipositive ion.
