Abstract
Five new lanthanide complexes, [Pr(HL1)(H2O)4]Cl2·2H2O (1), [Ho(HL1) (H2O)3]Cl2·2H2O (2), [Dy(HL1)(H2O)3]Cl2·2H2O (3), [Dy(H2L2)2(H2O)6]Cl3 (4) and [Ce(H2L3)(CH3CO2)2(H2O)2]·H2O (5), based on carboxylate ligands have been prepared. All complexes have been characterized via elemental analysis, single-crystal X-ray diffraction, powder X-ray diffraction and thermogravimetric analysis. According to single-crystal X-ray analysis, 1–3 and 5 are coordination polymers (CPs) with 1D zigzag chains, while 4 is a 0D structure. The 3D supramolecular structures of 1–4 are formed by the interaction of C/N − H···Cl hydrogen bonds and π···π stacking interactions. In addition, the luminescent and magnetic properties of 1–5 have been discussed.
