通过独特的反应合成了两种新型的二硝基乙腈铜配合物Cu（NH3）（4）（DNANT）（2）（1）和Cu（en）（2）（DNATN）（2）（2），并对其结构进行了表征。单晶X-射线结构分析表明，两种配合物中的Cu ~（2+）离子具有相似的四配位结构，但并不直接参与主要的能量负离子DNANT（-）。差示扫描量热法（DSC）研究表明，这两种配合物比FOX-7配合物具有更高的热稳定性和更低的感度，对RDX的分解具有良好的催化作用。(c)2013 Elsevier Inc. All rights reserved.
Two novel copper complexes of dinitroacetonitrile (DNANT), Cu(NH3)(4)(DNANT)(2) (1) and Cu(en)(2) (DNATN)(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 Cu2+ cations in the two complexes share a similar four-coordinated structure, which however does not directly involve the main energetic DNANT(-) 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.
