V. 60. N 1. P. 45-49. In this work crystal data of bis[1-(diaminomethylene)-thiouron-1-ium] sulfate is shown. This compound was characterized by IR spectroscopy and elemental analysis. The monocrystal of this compound was obtained and the structure was confirmed by single X-ray analysis. Moreover, the work describes potential application of synthesized compound. Comparative characteristics of thiourea and its known salts are demonstrated. It is known, that derivatives of thiourea have several tautomeric forms, which can be different in crystalline state or in solution. Therefore, changed scheme of the synthesis of 2-imino-4-thiobiuret is proposed. Elemental cell of crystal consists of two 1-(diaminomethylene)thiouron-1-ium cations and one sulfat anion. A full set of X-ray diffraction data was deposited in the Cambridge Structural Database (deposit CCDC 1421710) and it can be gotten from the site www.ccdc.cam.ac.uk/data_request/cif.
