Аннотация: The salt [NH3(CH2)(2)SS(CH2)(2)NH3][CuCl4] was obtained by crystallization after adding CuCl2 to cystamine (Cysta), solved in hydrochloric acid. The assumption of conserved disulfide connection (S-S) in the compound, made on the basis of infrared spectroscopy, is further supported by the crystal structure determined from X-ray powder diffraction data. The compound has an ionic structure. [CuCl4](2-) and CystaH(2)(2+) ions package in the form of inorganic and organic layers in the cell, interconnected through the formation of hydrogen bonds via NH3-groups and chlorine atoms of the complex [CuCl4](2-). Inorganic layers are additionally stabilized in the parquet package of [CuCl4](2-) ions which provides a Cu-distorted octahedral coordination. CystaH(2)[CuCl4] is stable in air up to 200 degrees C. Thermal decomposition occurs in several stages, accompanied by breaking of S-S bonds, releasing of the organic component and yielding CuO. (C) 2015 International Centre for Diffraction Data.
