| Abstract: | Reactions of three tetrazole carboxylate ligands, namely 5-(4-pyridyl)tetrazole-2-acetic acid (Hpytza), 1,3,5-tris(tetrazol-5-yl)benzene-N2,N2′,N2″-triacetic acid (H3tzpha) and 5-aminotetrazole-1-propanoic acid (Hatzpa) with Mn(NO3)2·6H2O in the presence of KOH afforded three new complexes, [Mn(pytza)2] (1), [Mn3(tzpha)2(H2O)12]·2CH3OH·10H2O (2) and [Mn(atzpa)2(H2O)2] (3), respectively. These complexes were characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. Complex 1 displays a three-dimensional network while 2 and 3 show one-dimensional chains. Furthermore, the luminescence properties of these complexes were investigated at room temperature in the solid state. |
