Darstellung und Kristallstruktur des Bis(2-amino-1-ammonioethan)hexasulfids [H3N-(CH2)2-NH2]2S6 /Synthesis and Crystal Structure of Bis(2-amino-1-ammonioethan)hexasulfide, [H3N—(CH2)2-NH2]2S6

Abstract

Bis(2-amino-1-ammonioethan)hexasulfide has been synthesized from ethylendiamine, sulfur and hydrogensulfide in ethanolic solution. It consists of unbranched chains S6 2- (helical all-trans-conformation) and monoprotonated ethylenediamine cations; the latter show the uncommon synclinical conformation. A remarkable system of N - H···S-bridges links the S6 2-chains to form an infinite array. It crystallizes in the space group P1̄ with a = 9.203(4) Å, b = 9.921(4) Å, c = 15.583(5) Å, α = 93.03(3)°, β = 90.04(3)°, γ = 79.07(3)°
