Abstract
Reactions of three tetrazole containing carboxylic acid ligands, namely, Hpztza, Htzpya, and Hpytza [Hpztza = 5-(2-pyrazinyl)tetrazole-2-acetic acid, Htzpya = 3-(5-tetrazolyl)pyridine-1-acetic acid, Hpytza = 5-(3-pyridyl)tetrazole-2-acetic acid] with NdCl3·6H2O under hydrothermal conditions, afforded the complexes [Nd(pztza)2(H2O)6]·pztza·3H2O (1), [Nd2(tzpya)2(H2O)12]Cl4·2H2O (2), and [Nd(pytza)2Cl(H2O)2] (3). The compounds were structurally characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. X-ray diffraction analyses revealed that compound 1 displays a mononuclear structure, 2 shows a dinuclear structure, and 3 features a 1D polymeric chain structure via pytza as linker. Furthermore, the luminescent properties investigated at room temperature in the solid state show that compound 2 has an obvious decrease in its luminescence, when compared to the ligand.
