摘要：

The thermal decomposition in air of omicron-phthalates of Y and the lanthanides from La(III) to Lu(III) (excluding Pm) was studied. The hydrated complexes Ln2(C8H4O4)3.nH2O (n = 2-16) lose water of crystallization in one (Y, Ce, Sm-Ho, Yb and Lu), two (Pr, Tm) or three steps (La, Nd, Er), then anhydrous complexes decompose directly to oxides or with intermediate formation of oxycarboxylates (La, Pr, Nd). The anhydrous complexes of La-Dy undergo polymorphic transformation on heating.
