Abstract

Two energetic complexes, Fe2II(DTMone)2(H2O)6 (1) and Fe2IIIO(DTMone)2(H2O)12 (2) [H2DTMone = di(1H-tetrazol-5-yl) methanone] were synthesized and characterized by FT-IR spectroscopy, elemental analysis, and single-crystal X-ray diffraction. The coordination complex (1) and (2) belong to the P21/n and P1 space group, respectively. Both Iron cations are six-coordinated in octahedral fashion, by N atoms and O atoms. However, the O atoms of (2) have one free atom which is different from (1). The structure of complex (2) is analogous to two dimension structure due to the oxygen ligands participating in the coordination. Their thermal stabilities were investigated by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). Additionally, the DSC measurements display that the dehydrated polymers possess excellent thermal stability, and the thermal decomposition peak temperature is as high as 285 °C. The sensitivities to external stimuli were determined with BAM standard methods as for impact >40 J (TNT,15J) and for friction >360 N.
