Crystal structure of 1,4-bis(2-azidoethyl)piperazine-1,4-diium dichloride trihydrate, C8H18N8Cl2 ⋅ 3 H2O

“…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].…”

“…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(2azidoethyl)piperazine-1,4-diium dichloride. We obtained the title compound by almost the same method but obtained 1,4-bis(2-azidoethyl)piperazine-1,4diium dichloride trihydrate at a low temperature.…”
