Abstract

Four hexanuclear lanthanide salen complexes [Ln<sub>6</sub>(L<sup>1</sup>)<sub>4</sub>(OH)<sub>4</sub>(MeOH)<sub>4</sub>]·2Cl·4MeOH (Ln = Nd (<b>1</b>), Tb (<b>2</b>)), [Eu<sub>6</sub>(L<sup>2</sup>)<sub>4</sub>(OH)<sub>4</sub>(MeOH)<sub>2</sub>(EtOH)<sub>2</sub>(H<sub>2</sub>O)<sub>2</sub>]·2Cl·3EtOH·H<sub>2</sub>O (<b>3</b>), and [Er<sub>6</sub>(L<sup>2</sup>)<sub>4</sub>(OH)<sub>4</sub>(EtOH)<sub>2</sub>(H<sub>2</sub>O)<sub>2</sub>]·2Cl·2EtOH·MeOH·H<sub>2</sub>O (<b>4</b>) are formed from the reactions of LnCl<sub>3</sub>·6H<sub>2</sub>O and flexible Schiff base ligands H<sub>2</sub>L<sup>1</sup> and H<sub>2</sub>L<sup>2</sup> (H<sub>2</sub>L<sup>1</sup> = <i>N</i>,<i>N</i>′-bis­(3-methoxysalicylidene)­(propylene-2-ol)-1,3-diamine, H<sub>2</sub>L<sup>2</sup> = <i>N</i>,<i>N</i>′-bis­(salicylidene)­(propylene-2-ol)-1,3-diamine). The structures of <b>1</b>–<b>4</b> were determined by single crystal X-ray crystallographic studies, and their luminescence properties were determined
