Structurally Isomeric Ditopic 2-Mercaptobenzoxazole and 2-Hydroxybenzothiazole as Ligands for Design of 2D Sodium-Based Luminescent Coordination Polymers

Novel ditopic centrosymmetric soft-base ligands - 3,7-dihydrobenzo[1,2-d:4,5-d']bis(oxazole)-2,6-dithione (H2L1) and 3,7-dihydrobenzo[1,2-d:4,5-d']bis(thiazole)-2,6-dione (H2L2) have been obtained in one-pot way. Both compounds form 2D coordination polymers (CPs) by the reaction of free ligands...
