A one-dimensional coordination polymer based on novel radical anion ligand generated in situ: Notable magnetic and luminescence properties

A one-dimensional Zn(II) radical anion coordination polymer, [ZnCl(obip(center dot))](n) (Hobip = 2,3'-bimidazo[1,2-a]pyridin-2'(3'H)-one) (1) was synthesized by a hydrothermal reaction between Zn(ClO4)(2)center dot 6H(2)O and hydrochloride salt of imidazo[1,2-a]pyridin-2(3H)-one, in which the radical anion ligand ([obip](center dot-)) was generated in situ by aldol condensation and then deprotonation. The Compound 1 presents strong antiferromagnetic Coupling between paramagnetic radical species and notable greenish yellow-red fluorescence emission.
