The reactions of N-diethylaminothiocarbonyl-benzamidines Et 2 N-C(S)-N=C(NHR)-Ph (1: R = Ph, 2: R = C 3 H 7 , 3: R = H) with gold(III) compounds were studied. Treatment of 1 and 2 with equivalent amounts of tetrachlorogold acid gives 2,3-substituted 5-diethylamino-1,2,4- thiadiazoliumdichloroaurates(I) (1a, 2a). With tetrachlorogold acid in excess 1 yields 2,3-diphenyl- 5-diethylamino-l,2,4-thiadiazolium-tetrachloroaurate(III) 1b. With 3 and Na[AuCl 4 ] bis(3-phenyl-5- diethylamino-1,2,4-thiadiazolium)-chloride-tetrachloroaurate(III) 3b is produced. The structures of la, 2a and 3b were investigated by X-ray structure analysis. In la and 2a the dichloroaurate(I) ions are linear. In the 1,2,4-thiadiazolium cations the N-C-bond lengths alternate characteristically. In 3b the tetrachloroaurate(III) ion is square planar. The 1,2,4-thiadiazolium cation shows a different alternation of N-C bond lengths in comparison with la and 2a which suggests changes in the thiadiazolium ring in 3b to a tautomeric form as confirmed by the localization of the H atom at the N atom in ring position 4 instead of ring position 2. The structures of 1a, 1b, 2a and 3b were confirmed by elemental analysis, ES-MS, FAB-MS,  1 H and  13 C NMR and IR spectroscopy.
