Three new alkaline earth coordination compounds based on 5-(2-pyrimidyl)tetrazole-2-acetic acid

• Hpymtza was prepared.
• Three new compounds were prepared.
• The luminescent properties were investigated.

Reactions of Hpymtza (Hpymtza = 5-(2-pyrimidyl)tetrazole-2-acetic acid) with MCl2 (M = Mg(II), Sr(II), Ba(II)), produced three new coordination compounds, [Mg(H2O)6]·2pymtza·H2O (1), [Sr(pymtza)2(H2O)2]·4H2O (2), [Ba(pymtza)2(H2O)4]·H2O (3), These compounds were characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. Compound 1 shows a mononuclear structure while 2 and 3 reveal 1-D structures via bridging pymtza as linker. Furthermore, the luminescent properties of 1–3 were investigated at room temperature in the solid state.

Three new alkaline earth coordination compounds containing Hpymtza ligand have been synthesized. Compound 1 shows a mononuclear structure while compounds 2 and 3 reveal 1-D structures via bridging pymtza as linker. The luminescence properties of 1–3 were investigated at room temperature in the solid state.Figure optionsDownload as PowerPoint slide
