Description:
Reactions of H 2 tza (H 2 tza = 1H-tetrazolate-5-acetic acid) with Mg(NO 3 ) 2 · 6H 2 O, Ca(NO 3 ) 2 · 4H 2 O, or Ba(NO 3 ) 2 with the presence of KOH under hydrothermal conditions, produced three new coordination compounds, [ M (tza)(H 2 O) 2 ] ( M = Mg ( 1 ), Ca ( 2 ), Ba ( 3 )). These compounds were structurally characterized by elemental analysis, IR spectroscopy, and single-crystal X-ray diffraction. Compounds 1 and 3 display 2D structures, whereas 2 reveals a 1D structure with bridging tza ligand molecules as linkers. Furthermore, the luminescence properties of 1 – 3 at room temperature in the solid state were also investigated. The results show that the nature of metal ions play an important role in governing the molecular frameworks of 1 – 3 , and the strong coordinate abilities of carboxylate and tetrazolate group, endow tza with abundant coordination modes.
