摘要

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 NdCl_3·6H_2O under hydrothermal conditions, afforded the complexes [Nd(pztza)_2(H_2O)_6]· pztza·3H_2O (1), [Nd_2(tzpya)_2(H_2O)_(12)]Cl_4·2H_2O (2), and [Nd(pytza)_2Cl(H_2O)_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.
