A major challenge in energetic materials research is the development of compounds that simultaneously exhibit high density, high heats of detonation, excellent detonation performance, and acceptable safety characteristics through efficient incorporation of energetic functionalities into compact frameworks. In this regard, reaction conditions play a critical role in governing the self-assembly of energetic ligands with metal ions and thereby influencing the architecture and properties. Herein, two nitrate-containing energetic coordination compounds, [Ni3(TATa)6(H2O)6]·6NO3(Ni-ECC) and [Cu(TATa)2(NO3)3]·NO3(Cu-ECC), were synthesized and characterized by infrared spectroscopy, TGA-DSC, elemental analysis, PXRD, and single-crystal X-ray diffraction. Evaluation of their properties revealed detonation velocities of 7222 and 8634 m s-1, respectively. Notably, Cu-ECC possesses a solvent-free three-dimensional dense supramolecular framework with a crystal density of 2.04 g cm-3 and reduced impact and friction sensitivities of 20 J and 360 N. Its detonation performance (VOD = 8634 m s-1; DP = 36.4 GPa) approaches that of RDX, placing it among the promising ECCs reported to date. Hirshfeld surface and fingerprint analyses indicate that noncovalent interactions stabilize nitrate ions and reinforce structural integrity. Furthermore, Cu-ECC produced a 3.4 cm dent in a 5 mm lead plate in a detonation test, demonstrating potential as a secondary explosive.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...

The nitrous acid is unstable. Hence, it is formed in situ from a solution of sodium nitrite and cold aqueous acids such as hydrochloric or sulfuric acid. In an acidic solution, the –OH group of nitrous acid undergoes protonation to give oxonium ion, followed by water loss...

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
