Beschreibung:
<jats:p>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 2<jats:sub>1</jats:sub>2<jats:sub>1</jats:sub>2<jats:sub>1</jats:sub>, Z = 4. By hydrogen bonding the hydrogensulphate ions form chains of weakly helical structure.</jats:p>
