Abstract

Tractable (soluble) linear transition metal coordination polymers in which the metal ions are a necessary part of the backbone (and without which the polymer will stay intact) have proven difficult to synthesize.1-6 Bis(tetradentate) Schiff-base ligands coupled with zirconium(IV) ions large enough for eight- coordination can be used to overcome this insolubility,7-8 and recently an analogous soluble cerium(IV) Schiff-base polymer has been prepared.9 Although a number of reports had appeared regarding polymeric systems in which lanthanide metal ions are attached to a branch of a polymer chain10-14 or solid state species that either remain insoluble in all solvents or fall apart into small molecules when dissolved,15-17 soluble linear polymers with lanthanide ions in their backbone had been lacking prior to our study of catena-poly [cerium(IV)-µ-N,N′,N″,N‴-tetrasalicylidene(3,3′-diaminobenzidinato)-O,-N,N′,O′:O″,N″,N‴ ,O‴], [Ce(tsdb)]n.9
