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

摘要

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)]center dot 2pymtza center dot H2O (1), [Sr(pymtza)(2)(H2O)(2)]-4H(2)O (2), [Ba(pymtza)(2)(H2O)(4)]center dot 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. (C) 2014 Elsevier B.V. All rights reserved.
