On thermal decomposition of thiocarbamide complexes of thulium, ytterbium, lutetium, yttrium

Thiocarbamide complex compounds of the following composition: M(C3H5O2)3xCs(NH2)2xxH2O, where M is Tm, Yb(x = 3), Lu (x = 1) and Y (x = 3.5), have been obtained. The thermography, thermogravimetry, chemical analysis and IR-spectroscopy techniques have been used to determine the composition of the intermediate products obtained as a result of thermal decomposition of these compounds. A thermolysis diagram is proposed on the basis of the experimental data
