Synthesis and characterization of La methanesulfonate coordination compounds with pyridine-N-oxide and 2-, 3-, and 4-picoline-N-oxide
Synthesis, characterization and thermal (TG, DSC, GC-MS) study of the coordination compounds La(MS)(3).(pyNO)(2), La(MS)(3).(2-picNO)(2), La(MS)(3).(3-picNO)(2) and La(MS)(3).(4-picNO)(1.5).H2O are reported. The observed thermal stability trend is 2-picNO < pyNO < 3-picNO < 4-picNO. Under heating, the rupture of the La-N-oxide bond is promoted, together with fragmentation of the N-oxide molecule.
