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.
