The synthesis, characterization and a thermal (TG and DSC) study of the coordination compounds Gd(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
