Nastajanje i karakterizacija bistiourea cinkovoga formata
Formation of a new complex in the Zn(HCOO)2-CS(NH2)2-H2O system at 25 °C was established by the solubility method. Its composition was determined to be Zn(HCOO)2 * 2CS(NH2)2.
The bisthiourea zinc formate (BTZF) is an incongruently soluble salt at 25 °C. It has been characterized by X-ray powder diffraction, IR spectroscopy and thermal analysis. The infrared spectra reveal that thiourea forms a zinc-sulfur bond. Thermal decomposition at a temperature of 400 °C yields ZnS.Ustanovljeno je da metodom topljivosti u sustavu Zn(HCOO)2-CS(NH2)2-H2O pri 25 °C nastaje novi kompleksnispoj. Određivanje sastava pokazalo je da se radi o Zn(HCOO)2 * 2CS(NH2)2. Pri 25 °C bistiourea cinkov format (BTZF) neprimjereno je topljiva sol. Spoj je opisan rentgenskom difrakcijom na prahu, IR spektroskopijom i termičkom analizom. U infracrvenom spektru otkrivena je vrpca koja odgovara vezi cink-sumpor. Termički raspad spoja završava kod temperature 400 °C pri čemu zaostaje cinkov sulfid
