DE FARIAS %J Journal of the Serbian Chemical Society %D 2005 %I Serbian Chemical Society %X The synthesis, characterization and a thermal (TG and DSC) study of the coordination compounds Gd(MS)3,(py-NO)2, Gd(MS)3,(2-picNO)2, Gd(MS)3,(3-picNO)2, Gd(MS)3,(4-picNO)2, Lu(MS)3,(py-NO)2,2H2O, Lu(MS)3,(2-picNO)1.5,H2O, Lu(MS)3,(3-picNO) and Lu(MS)3,(4-picNO)2 are reported (MS = methanesulfonate, py-NO = pyridine-N-oxide, 2-picNO, 3-picNo and 4-picNO are 2-, 3- and 4-picoline-N-oxides, respectively). The observed thermal stability trend is: 2-picNO < py-NO < 4-picNO < 3-picNO for Gd and 2-picNO < 4-picNO < 3-picNO < py-NO for Lu. It was shown that the release of ligand molecules (endothermic) is followed by the thermal degradation of the ligands (exothermic). %K gadolinium %K lutetium %K coordination compounds %K thermogravimetry %U http://www.shd.org.yu/HtDocs/SHD/vol70/No8-9/JSCS_V70_No8-9-03.pdf
