Description:
Different kinds of counterions (such as NO 3 – , ClO 4 – , and Cl – ) play a special role in controlling the framework of coordination compounds. Using this strategy, 5-aminotetrazole-1-propionic acid (Hatzp) was selected to react with praseodymium(III) nitrate or perchlorate in the same solvent system, producing two different coordination compounds, [Pr 2 (atzp) 4 (H 2 O) 8 ] · 2NO 3 · 2H 2 O ( 1 ) and [Pr 2 (atzp) 6 (H 2 O) 2 ] · H 2 O ( 2 ). These compounds were structurally characterized by elemental analysis, IR spectroscopy, and single-crystal X-ray diffraction. X-ray diffraction analysis revealed that compound 1 displays a dinuclear structure, whereas 2 shows a one dimensional zigzag chain framework. Furthermore, the luminescence properties of compounds 1 and 2 were investigated at room temperature in the solid state.
