Reactions of isopropoxides of praseodymium, neodymium and samarium with bifunctional tridentate and tetradentate schiff bases (i.e. salicylidene‐O‐aminophenol and bis‐salicylaldehyde ethylenediamine) have been carried out in benzene in different stoichiometric ratios resulting in the formation of products with the formula M(OPr i )(C 11 H 9 NO 2 ), M(C 13 H 9 NO 2 )(C 13 H 10 NO 2 ). M 2 (C 13 H 9 NO 2 ) M(OPr i )(C 15 H 14 N 2 O 2 ), M(C 16 H 14 N 2 O 2 )(C 16 H 15 N 2 O 2 ) and M 2 (C 16 H 14 N 2 O 2 ) 3 (where M stands for Pr, Nd and Sm). The products were found to be yellow to orange solids soluble in benzene and alcohol. The absorption spectra of these complexes were also recorded in methanol.
