Metal complexes having the potential to modify the burn rate of rocket propellants are described. These are the diaminoglyoxime (DAG) complexes: Co(DAG–H) 2 ·DAG, Cu(DAG–H) 2 ·DAG, Ni(DAG–H) 2 and Pd(DAG–H) 2 . The thermal decomposition was characterized by DSC, TGA and IR spectroscopy at a heating rate of 5°C/min, and by fast thermolysis/FTIR spectroscopy at 100–250°C/s. The M(DAG–H) 2 complexes are more thermally stable than M(DAG–H) 2 ·DAG. However, all of the compounds produce highly thermally stable residues which would be expected to retard the heat and mass transfer at a burning surface. The residues most closely resemble coordination complexes of the metal and polymeric cyclic azine compounds. The crystal and molecular structure of the previously unreported complex Ni(DAG–H) 2 ·HCL is described.
