Y, Zhang DW. Synthesis and characterization of trans-
temperature. Among the anhydrous complexes, 2 is the
most stable one in the inert atmosphere, and the complex
stability is decreasing in the order 2 [ 1 [ 3. The thermal
decomposition in all cases is continuous without stable in-
termediate formation. The thermal degradation of 1 and 3
in air is followed by the burning of the samples, and
therefore, their thermal curves are deformed. By on-line
coupled TG/DTA-MS measurements, beside the evapora-
tion of water and HCl, the fragments characteristic for the
aromatic rings of the ligands were detected. All compounds
show bacteriostatic effect. Their antimicrobial activity is
decreasing in the order: 3 [ 1 [ 2, and it is in agreement
with their thermal stability. The new compound 3 with the
lowest stability shows the highest bacteriostatic effect.
