Abstract
A pyridine derivative 6,7-dihydropyrido(2,3-d)pyridazine-5,8-dione (H2PDH) and oxalic acid (H2ox) are reacted with dysprosium oxide to develop a new 2-D dysprosium–organic complex [Dy(PDH)(ox)0.5(H2O)2]. The single-crystal structure reveals that acylamino oxygens and coordinated waters develop a 3-D supramolecular network, which is composed of 2-D layers, and each 2-D layer is formed by 1-D Dy–H2O–ox chains linked by tridentate PDH2− ligands. The complex exhibits metal-centered luminescence with yellowish blue emission. The energy transfer mechanism and photoluminescence are also investigated.
