Abstract

Five homobimetallic compounds derived from indacene and p-phenylene ligands with different Fe–Fe distances have been synthesized. The catalytic effect on the thermal decomposition of Ammonium Perchlorate (AP) of each complex is analyzed, establishing comparisons with catocene (Cat) and ferrocene (Fc). Cyclic voltammetry showed quasi-reversible redox potential with higher electron-transfer ability than ferrocene and catocene. An anti-migration study of these compounds is carried out, compared with those of Cat and Fc. Compound 5, bearing a higher molecular weight, displayed a better anti-migration performance than catocene and ferrocene. In addition, the synthesized compounds have shown a shift on the peak temperature to lower values as well as an increase in the released heat values during thermal decomposition of AP.
