The new dual anion solvent-free nickel complex based on the pyridine-4-carbohydrazide ligand

Based on the ideas of coordination and design chemistry, we propose a new strategy to balance the energy and sensitivity conflict by synthesizing dual anion structures in the realm of energetic complex compounds. Therefore, a novel solvent-free complex, [Ni(4-PDCA) 2 (NO 3 ) 2 ](ClO 4 ) 2 ( ECCs-1 ), which has a six-coordinated octahedral structure and contains dual anions, was synthesized. The structure was identified by IR, EA and single-crystal XRD. To the best of our knowledge, it is the first reported dual anion structure that exhibits excellent insensitivity with acceptable thermal stability and detonation performance. The first dual anion nickel complex has been prepared, and its structure and properties were studied. This complex possessed excellent detonation performance ( D = 6350 m s −1 and P = 16.7 GPa) and insensitivity (IS = 40 J and FS = 360 N).
