We reported the synthesis of a novel bimetallic compound with the formula [(Cp*Ru)₂-IF] derived from 6,12-dihydroindeno[1,2-b]fluorene ligand (IFH₂). This compound was characterized by ¹H and ¹³C NMR, elemental analysis, FT-IR, and UV-vis.

The bimetallic compound was tested as a burning rate catalyst on the thermal decomposition of ammonium perchlorate. It was assessed by differential scanning calorimetry technique (DSC) analysis to understand its catalytic behavior further. [(Cp*Ru)₂-IF] shows a decrease in the decomposition temperature of AP to 381°C, increasing the energy release to 1271 J•g⁻¹. In addition, this compound leads to the lowest activation energy (20.7 kJ•mol⁻¹), suggesting a suitable and competitive alternative to be used as a modifier for composite solid propellants.

我们报道了一种由 6,12-二氢茚并[1,2-b]芴配体 (IFH _{2 ) 衍生的分子式 [(Cp*Ru) 2} -IF]的新型双金属化合物的合成。该化合物通过¹ H 和¹³ C NMR、元素分析、FT-IR 和 UV-vis 进行了表征。

双金属化合物作为燃烧速率催化剂对高氯酸铵的热分解进行了测试。通过差示扫描量热技术 (DSC) 分析对其进行评估，以进一步了解其催化行为。[(Cp*Ru) ₂ -IF]表明AP的分解温度降低至381°C，能量释放增加至1271 J•g ^-1。此外，该化合物的活化能最低（20.7 kJ•mol ^-1），表明它是一种合适且具有竞争力的替代品，可用作复合固体推进剂的改性剂。
