3,5-Diphenyl-1,2-dithiolium-hydrogensulfat – Bildung und Struktur / 3,5-Diphenyl-1,2-dithiolium Hydrogensulphate – Synthesis and Structure

Abstract

3,5-Diphenyl-1,2-dithiolium hydrogensulphate was prepared by the reaction of bis(thiodibenzoylmethanato)-nickel(II) with thionyl chloride in acetonitrile solution. The compound was characterized by X-ray structure determination (1261 observed, independent reflexions, R = 0,056). Crystal data: a = 543,1(1), b = 1605,7(1), c = 1678,9(2) pm; space group P 212121, Z = 4. By hydrogen bonding the hydrogensulphate ions form chains of weakly helical structure.
