Structural features and near infra-red (NIR) luminescence of isomeric Yb(iii) bipyridyl-N,N′-dioxide coordination polymers

Abstract

The synthesis and structural characterization of a series of lanthanide complexes formed from YbX₃ salts (X = NO₃⁻ or CF₃SO₃⁻) and the isomeric 4,4′-bipyridine-N,N′-dioxide (4,4′-bpdo) or 3,3′-bipyridine-N,N′-dioxide (3,3′-bpdo) ligands has been undertaken by X-ray crystallography.
