The synthesis and structural characterization (by electronic, IR, EPR
spectra and TD analysis) of trinuclear complexes with general formula
: { Cu[La(AO)3]2}X(2) . nH(2)O (X = Cl; n = O; X = NO3, n = 2: X = CH3
COO, n = 1 and AOH = 3-amino-1-propanol) are presented. Acetate polynu
clear complex is a precursor of La2O3 . CuO mixed oxide, obtained by '
'hydrolysis method''.
