R. Mrozek et al., THERMAL-DECOMPOSITION OF RARE-EARTH COMPLEXES WITH 2-AMINO-3,5-DICHLOROBENZOIC ACID, Synthesis and reactivity in inorganic and metal-organic chemistry, 27(5), 1997, pp. 707-720
The conditions of the thermal decomposition of the 2-amino-3, 5-dichlo
robenzoates of Y and lanthanides have been studied. During heating in
air, the dihydrated complexes Ln(C6H2Cl2NH2COO)(3) . 2H(2)O decompose
in three steps, with the exception of the yttrium(III) and cerium(III)
complexes, which decompose in two steps. In the first step the comple
xes lose two molecules of water and next decompose to the oxides with
intermediate formation of LaOCl. The complexes of Y(III) and Ce(III),
when heated, are dehydrated and then decompose to the oxides. The mode
of metal-ligand coordination is discussed.
