Abstract

A set of three potentially bridging ligands containing two tridentate chelating N, N′, O-donor (pyrazole–pyridine–amide) donors separated by an o, m, or p-phenylene spacer has been prepared and their coordination chemistry with lanthanide (III) ions investigated. Ligand L1 (p-phenylene spacer) forms complexes with a 2: 3 M: L ratio according to the proportions used in the reaction mixture; the Ln2 (L1) 3 complexes contain two 9-coordinate Ln (III) ...
