We describe the structure
and properties of [Zn(C6H4N5)N3]n,
a new nonporous three-dimensional high-energy metal–organic
framework (HE-MOF) with enhanced thermal stability. The compound is
synthesized by the hydrothermal method with in situ ligand formation
under controlled pH and characterized using single-crystal X-ray diffraction,
elemental analysis, and Fourier transform infrared. The measured detonation
temperature (Tdet = 345 °C) and heat
of detonation (ΔHdet = −0.380
kcal/g) compare well with commercial explosives and other nitrogen-rich
HE-MOFs. The velocity and pressure of denotation are 5.96 km/s and
9.56 GPa, respectively. Differential scanning calorimetry analysis
shows that the denotation of [Zn(C6H4N5)N3]n occurs via a complex
temperature-dependent mechanism.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
