•Synthesis and characterization of novel lanthanide compounds•Multifunctional triazole ligand has been synthesized.•Luminescence of LCPs has been carried out.•Different auxiliary ligands can affect the emission properties.
Two series of lanthanide coordination polymers, {[Ln2(tabc)4(C2O4)(H2O)5]·H2O}n (Ln = Nd (1), Sm (2), Eu (3), Htabc = 4-(1–1,2,4-triazolyl)benzoic acid) and {[Sm(tabc)(1,2-pdc)(H2O)2]·2H2O}n (4), have been constructed via hydrothermal conditions through adding different auxiliary ligands. Compounds 1–3 are two dimensional coordination layer comprised of {Ln1(COO)2} chains and {Ln2(COO)2} dinuclear units which are connected by oxalate groups, whereas compound 4 is one dimensional chain containing {Sm2(COO)2} dinuclear units. The IR spectra and thermal stabilities of all compounds have been studied in detail. Compound 3 shows characteristic emission of Eu3 + ions, and it is noteworthy that the luminescent properties for 2 shows no emission peaks whereas that for 4 exhibits characteristic absorption bands of Sm3 + ions.CCDC: 1478487, 1478488, and 1478495
