Abstract

A new energetic compound [Zn (CHZ)₃] (ClO₄)₂ was synthesized in aqueous solutions of carbohydrazide and Zn (ClO₄)₂. Single crystals suitable for X-ray analysis were obtained. The compound was characterized by differential scanning calorimetry (DSC), thermal gravimetry-differential thermal gravimetry (TG-DTG) and single crystal X-ray diffraction analysis. The crystal belongs to a monoclinic system with P2 (1) /n space group and cell parameters of a=1.0005 (2) nm, b=0.8428 (1) nm, c=2.1218 (4) nm, β=100.948 (3)°, V=1.7566 (5) nm³, D_c=2.021 g/cm³, Z=4, F (000) =1088, R₁=0.0341 and ωR₂=0.0729. The Zinc (II) cation is coordinated with carbonyl O atoms and N atoms from carbohydrazide forming a six-coordinated ring structure. [Zn (CHZ)₃] (ClO₄)₂ can resist heat up to 270°C. An intense continuous exothermic decomposition process occurs in the range of 280~340°C. The sensitivity test results reveal that [Zn (CHZ)₃] (ClO₄)₂ was insensitive to impact, friction and flame stimuli.
