Abstract

Four novel 3d–4f heterometallic coordination polymers [Dy4Mn(PDA)6(SO4)2 (H2O)4]·13H2O (1) and [Ln4M(PDA)4(SO4)2(INA)2(H2O)8]·5H2O [Ln = Gd, M = Mn (2); Ln = Eu, M = Zn (3); Ln = Tb, M = Zn (4); PDA = pyridine-2,6-dicarboxylate; INA = isonicotinate] have been hydrothermally synthesized and structurally characterized. Compound 1 possesses a 1D chainlike structure with the tetranuclear [Dy4(PDA)6(SO4)2(H2O)2] “metalloligand” linking the adjacent Mn atoms. Compounds 2–4 are isostructural and possess a 2D heterometallic layer network with a (4,4) connected topology. Furthermore, the magnetic and luminescent properties of compounds 1–4 were investigated.
