1D Structure Sodium Coordination Anion based on [5-(Dinitromethylene)-4,5-dihydro-1 H-tetrazole]: Syntheses, Structures, and Thermal Behavior.

The ten-coordinate complex, (HATr)[Na(DNMz)] ·H₂O ( 1) was synthesized by reaction of 5-(dinitromethylene)-4,5-dihydro-1 H-tetrazole (DNMz), sodium hydroxide, and 3-hydrazinium-4-amino-1,2,4-1 H-triazolium dichloride (HATr) in aqueous solution and characterized by various physico-chemical techniques. Complex 1 is an energetic material with a nitrogen content of 51.2 % and a decomposition temperature of 128.9 °C. The molecular structure of complex 1 crystallizes in the monoclinic system with P2(1)/ c group and shows an infinite 1D chain structure. The heat of formation was determined as -122.27 kJ ·mol^-1 by using bomb calorimetry. In addition, the kinetic parameters were studied by Kissinger's and Ozawa-Doyle's methods. [ABSTRACT FROM AUTHOR]
