Oxide Stabilized Lanthanide

A series of new mixedligand lanthanide complexes [ln(hfa) 3 (4cpyno)] 2 (ln = sm iii ho iii and tm iii; hfa = hexafluoroacetylacetonate; 4cpyno = 4cyanopyridine noxide) have been synthesised by treating the corresponding lanthanide hexafluoroacetylacetonates with 4cpyno (molar ratio 1:1) in chloroform.Singlecrystal xray analysis revealed that [tb(hfa) 3 (4.
