Abstract

The first coordination polymer of a bridging radical 1,2,3,5-dithiadiazolyl ligand is reported. Upon coordination with the La(hfac)₃ fragment, the paramagnetic 4-(benzoxazol-2′-yl)-1,2,3,5-dithiadiazolyl (boaDTDA) ligand forms a one-dimensional (1D) alternating –[La(hfac)₃–boaDTDA]_n– polymer exhibiting ferromagnetic (FM) coupling between the radicals, mediated through the diamagnetic La^III ion (hfac = 1,1,1,5,5,5-hexafluoroacetylacetonato).
