Molekül- und Kristallstruktur der Verbindung 8-(n-Butylaminophenyl- methyliden)-1,2,3,4,5,6,7-heptathiocan / Molecular and Crystal Structure of 8-(n-Butylaminophenyl- methylidene)-1,2,3,4,5,6,7-heptathiocane

Abstract

By the reaction of acetophenone with sulfur and primary amines yellow-coloured crystals of the title compound are formed. It crystallizes in the monoclinic space group P21/n with lattice constants a = 1309.9(2) pm, b = 926.5(2) pm, c = 1582.2(2) pm and β = 114.00(1)°. The structure of the eight-membered heptathiocane ring is characterized by a crown confor­mation. The range of the S-S distances [204.4(1)-207.3(1) pm], the S-S-S bond angles [107.2(1)- 109.0(1)°] and the S-S-S-S torsion angles [93.2(1)-97.7(1)°] is comparable to those observed in α-, β- and γ-sulfur.
