Abstract
A new polynitrile, N,N,N′,N′-tetra(2-cyanoethyl)-1,4-bis(3-aminopropyl)piperazine, was synthesized by the nucleophilic addition reaction of 1,4-bis(3-aminopropyl)piperazine and acrylonitrile for the first time. The title compound was characterized by elemental analysis, IR spectrum, and its crystal structure determined by X-ray single-crystal diffraction. The compound crystallizes in the monoclinic system with space group P2 1/c and a = 8.6195(12), b = 9.300(14), c = 16.221(2) Å, β = 97.824(2)°, V = 1288.2(3) Å3, D c = 1.064 g cm−3, M r = 412.59, Z = 2, F(000) = 448, μ = 0.067 mm−1. The TG–DTA analysis revealed that the title compound possesses relatively good thermal stability under 220 °C.
