Studies on sodium polymers based on di(1H-tetrazol-5-yl) methanone oxime

[Na(Hbto)(H2O)(2)center dot 2H(2)O](n) (1), [(NH3OH)(2)Na-2(bto)(2)(H2O)(4)center dot H2O](n) (2) and [(NH3OH) Na(bto)(H2O)(2)](n) (3), eco-friendly coordination polymers, have been synthesized. The structures have been confirmed by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. The crystal results demonstrate that compound 1 exhibits an infinite 2-dimensional (2D) network metal-organic framework (MOF), whereas compounds 2 and 3 feature infinite 1-dimensional (1D) Na-polymer chain structures. Additionally, the DSC tests display that the dehydrated polymers possess excellent thermal stability, and their thermal decomposition temperatures are as high as 250 degrees C. The enthalpies of formation are calculated based on the experimental constant-volume energies of combustion. Non-isothermal kinetic and thermodynamic parameters are investigated through Kissinger's method as well as Ozawa's method. Furthermore, the yellow flame color of the prepared compounds are confirmed. The sensitivities toward impact (>40 J) and friction (>360 N) are investigated via standard methods.
