Fv. Dandawate et al., THERMAL, SPECTROSCOPIC AND MAGNETIC STUDIES OF SOME RARE-EARTH 3-HALOLAWSONEMONOXIMATES, Thermochimica acta, 241, 1994, pp. 103-111
The metal chelates of 3-chloro-, 3-bromo- and 3-iodo-derivatives of la
wsonemonoxime with La(III), Sm(III) and Dy(III) have been synthesised.
The thermal, spectral and magnetic properties of these chelates have
been investigated to study the effect of variation of the C-3-halo-sub
stituent on the chelating ability of the lawsonemonoxime. The energy o
f activation E(a) and the order of reaction n for the decomposition st
ages have been calculated using the Coats-Redfern relation.
