Source of material

Single crystal of 1,4-bis(2-azidoethyl)piperazine-1,4-diium dichloride trihydrate was obtained by slow evaporation from the 1,4-bis(2-azidoethyl) piperazine-1,4-diium dichloride aqueous solution at temperature of 10 °C.

Experimental details

In the crystal structure, all hydrogen atoms were obtained geometrically and refined using a riding model.

Comment

Amine azide compouds have higher density, positive enthalpy of formation than hydrazines, and their detonation products are also pollution-free. So they are ideal alternatives for hydrazine based fuels [3]. In recent years, more researchers have paid attention to the synthesis and performance of azide amine compounds, and synthesized a variety of amine azide compounds [4], [5], [6]. In 2018, Gao et al. [7] already synthesized an amine azide compound containing a piperazine ring with higher density and obtained the single crystal of 1,4-bis(2-azidoethyl)piperazine-1,4-diium dichloride.

We obtained the title compound by almost the same method but obtained 1,4-bis(2-azidoethyl)piperazine-1,4-diium dichloride trihydrate at a low temperature. Due to the presence of crystal water, a large number of hydrogen bonds exist, giving the compound a much better stability. Geometric parameters are similar to those already reported [7].
