A vacuum sublimation apparatus with a continuous temperature gradient (25–260 °C) along the tube (0–50 cm) at 2×10<SUP>−2</SUP> Torr (1 Torr≈133.322 Pa) was used. STTA (1,1,1-trifluoro-4-(2-thienyl)-4-mercapto-3-buten-2-one) and its metal chelates of Mn<SUP>II</SUP>, Fe<SUP>III</SUP>, Co<SUP>III</SUP>, Ni<SUP>II</SUP>, Cu<SUP>II</SUP>, Zn<SUP>II</SUP>, and Pd<SUP>II</SUP> sublimed quantitatively without thermal decomposition, while the chelates of Ag<SUP>I</SUP> and Cd<SUP>II</SUP> were accompanied by thermal decomposition.
