چکیده
|
Tetrazole–carboxylate ligands with both rigid tetrazole ring and flexible carboxylate group have a great potential in the construction of coordination architectures. here, we report four new samarium(iii) compounds based on four tetrazole–carboxylate ligands 5-(2-pyrimidyl)tetrazole-2-acetic acid (hpmtza), 5-aminotetrazole-1-propanoic acid (hatzpa), 5-(4-pyridyl)tetrazole-2-acetic acid (hpytza), and 3,3-di(1h-tetrazol-5-yl)pentanedioic acid (h4dtzpda), namely mononuclear [sm(pmtza)2(h2o)6]cl·3h2o (1), binuclear [sm2(atzpa)4(h2o)8](no3)2·2h2o (2), one-dimensional [sm(pytza)3(h2o)2]·2h2o (3) and [sm(hdtzpda)(h2o)4]·4h2o (4). the effect of different counter anion (clo4 −, cl−, no3 −) on the formation of such compounds was also investigated. furthermore, the luminescence of compounds 1–4 shows intraligand emission, whereas the characteristic peaks of sm3+ be overlapped.
