Abstract
Products of reactions of salts of d elements with formamidine disulfide dihydrochloride (FDSH2Cl2) in concentrated HCl and HBr solutions were synthesized and characterized. The following compounds were obtained: FDSH2[CuCl4] · H2O, FDSH2[CoCl4], FDSH2[ZnCl4], FDSH2[HgCl4], and FDSH2[HgBr4]. The identity of these compounds was confirmed by X-ray diffraction; their compositions were derived from the results of chemical analysis and thermal analysis. The IR and Raman scattering spectra of the compounds indicate the presence therein of FDSH22+ cation. It was established that FDSH22+ transforms into formamidindium trisulfide cation (NH2)2C-S-S-S-C(NH2)22+ upon storage in air in hydrochloric acid solution.
