✦ Synopsis

The 3,5-diamino-1,2,4_dithiazolium salts DADTX [X = Cl dHrO), Br, I, ClO,, Nor, fSO,(H,O)] have been prepared and their i.r. spectra investigated in relation to that of dithiobiuret and to the molecular structure of the thiouret hydrohalides. In the DADTX salts the dithiobiuret v(NH& and 6(NHz) bands are observed at about the same frequencies as in the ligand, the v(NH) and S(NH) bands are absent and the v(CN) and v(CS) bands are shifted to higher and lower frequencies, respectively, in agreement with a shortening of the CN and an elongation of the CS bonds and a new v(SS) band is observed in the 430-410 cm-' region.
