Abstract

Abstract: Two recently introduced concepts in the design of high-energy-density materials (HEDMs), namely Metal–organic frameworks (MOFs) and Chelating energetic material (CEM), have been applied in the synthesis of the energetic manganese (II) compound {[Mn(btm)(H2 O)3 ]2 ·H2 O}n (1 ) (H2 btm = bis(tetrazole)methane), cocrystalized by a dinuclear CEM and a 1D MOF, which is characterized by elemental analysis and FTIR spectroscopy. Single-crystal X-ray diffraction analysis revealed that1 crystallizes in the monoclinic space group P 21/c . The Mn 2+ was hexa-coordinated with two btm groups and three water molecules. Btm presents tridentate coordination modes. The thermal decomposition mechanism of1 was studied by differential scanning calorimetry (DSC). The non-isothermal kinetics parameters were calculated by the Kissinger's method and Ozawa-Doyle's method, respectively. Sensitivity tests revealed that1 is insensitive to mechanical stimuli.
