Methods of making and resultant compositions thereof, which include copper-oxalyldihydrazide-based complexes, such as pyrotechnic compositions, gas generants, and ignition materials, which are useful, for example, in inflatable restraint systems. Synthesis of one or more copper-oxalyldihydrazide complexes with nitrate and/or hydroxide counter ions provides a composition that may auto-ignite at a low enough temperature to be based with thermally sensitive gas generants. The present copper-oxalyldihydrazide complexes may also be used in conjunction with various oxidizers to produce compositions with sufficient energy to auto-ignite practically any known pyrotechnic composition.
