A Characterization of Nickel Aminoguanidine Perchlorate

ABSTRACT Nickel aminoguanidine perchlorate (NAP) is an energetic coordination compound originally disclosed in a 2010 patent, yet it remains uncharacterized in the peer‐reviewed literature. Despite this, it has attracted attention in informal settings as a potential lead‐free primary explosive. In this study, we present the first comprehensive analytical characterization of NAP, including its synthesis, structure, morphology, vibrational spectra, thermal behavior, and sensitivity. Spectroscopic data (Fourier‐transform infrared, Raman, and ultraviolet‐visible) support coordination of aminoguanidine to a central Ni 2 ⁺ ion, with perchlorate present as a non‐coordinated counterion. Thermal analysis indicates decomposition onset near 270°C. Notably, the mechanical sensitivity of NAP is strongly morphology‐dependent: as‐synthesized needle‐like crystals exhibit high impact sensitivity, while alternative crystallization strategies afford improved handling characteristics. These results provide a necessary foundation for scientific and forensic understanding of a compound that is gaining visibility outside traditional regulatory and research frameworks.
