Abstract
Based on the advantages of energetic complexes and cocrystallization, a novel energetic complex cocrystal [Mn(SCZ)3](TNR) (H2O) · [Mn(SCZ)2(H2O)(TNR)](H2O) (SCZ: semicarbazide, TNR: 2,4,6-trinitroresorcinol) was synthesized through a one-step reaction. This cocrystal contains equal units of [Mn(SCZ)2(H2O)(TNR)](H2O) and [Mn(SCZ)3]TNR(H2O). The molecules of the two units arrange mutually crosswise in the cocrystal and the benzene rings of TNR can form one-dimensional self-assemblies through π-π stacking. The thermal decomposition of the cocrystal is complicated with one endothermic process and three exothermic processes in the DSC curve. The complex [Mn(SCZ)2(H2O)(TNR)] · 3(H2O) was synthesized and the temperature of the major exothermic peak of the cocrystal is higher than observed for this complex.
