Unprecedented lanthanide (Ln)-radical loop-chain coordination polymers were achieved using multidentate pyridyl- or triazole- substituted nitronyl nitroxide ligands. Their magnetic units consist of ferromagnetic [Ln2Radical] moieties, leading for the dysprosium­(III) derivatives to slow relaxation of magnetization, which was found to be dependent on the heterocyclic ligands.
