Linear Conjugated Coordination Polymers Containing Eight-Coordinate Metal Centers

Abstract

Abstract Two linear coordination polymers are reported in which conjugated organic ligands and nonrigid eight-coordinate metal centers are linked to form macromolecules with molecular weights of greater than 104 Daltons. The tungsten(IV) chelate is an inert low-spin d2 species with four oxygen and four nitrogen donors per metal with two bidentate blocking ligands and one bis-bidentate bridging ligand. The zirconium(IV) chelate is rendered inert through the use of a bis-quadridentate Schiff-base ligand. Future possibilities and potential uses are also discussed.
