Title: Syntheses and characterizations of two new energetic copper–amine-DNANT complexes and their effects on thermal decomposition of RDX

Two novel copper complexes of dinitroacetonitrile (DNANT), Cu(NH{sub 3}){sub 4}(DNANT){sub 2} (1) and Cu(en){sub 2}(DNATN){sub 2} (2), have been synthesized for the first time through an unique reaction, and structurally characterized. The single-crystal X-ray structural analysis shows that the Cu{sup 2+} cations in the two complexes share a similar four-coordinated structure, which however does not directly involve the main energetic DNANT{sup −} anion. The differential scanning calorimetry (DSC) study reveals that the two complexes have higher thermal stability and lower sensitivity than the analogous FOX-7 complexes, and exhibit good catalytic action to the decomposition of RDX. - Graphical abstract: Cu(NH{sub 3}){sub 4}(DNANT){sub 2} (1) and Cu(en){sub 2}(DNATN){sub 2} (2) have been first synthesized through an unique reaction. Cu{sup 2+} ion shares a similar four-coordinated structure in the two complexes. Display Omitted - Highlights: • A new reaction is unexpectedly found, and reaction process was discussed in this work. • Cu(NH{sub 3}){sub 4} (DNANT){sub 2}and Cu(en){sub 2}(DNATN){sub 2} were first synthesized through an unique reaction. • The structures and properties of the two complexes were discussed in detail, and they all present good application performances. • The adjacent amino-hydrazino group in AHDNE exhibits high reactivity. The work is another typical examplemore » for the reactivity.« less
