Thermal studies on some lanthanide complexes

Thermal behaviour of a few lanthanide complexes of the type ML3(I) [M=Eu, G d; HL=4,4,4-trifluoro-1-(2-napthyl)-1,3-butanedione and EuL(3)0.5dmm dmm=2, 6-dimethylmorpholine(II)], has been investigated. From thermogravimetric (T G) curves, the decomposition pattern of the compounds has been analysed on the basis of mass loss data. The order and activation energy of the thermal decomposition reactions have been elucidated. From differential thermal an alysis (DTA) studies, the heat of reaction and rate of thermal decompositio n reaction have been enumerated.
