Reactions of the isomeric ligands Hpztza [Hpztza = 5‐(2‐pyrazinyl)tetrazole‐2‐acetic acid] and Hpmtza [Hpmtza = 5‐(2‐pyramidyl)tetrazole‐2‐acetic acid] with TbCl 3 · 6H 2 O or DyCl 3 · 6H 2 O under solvothermal conditions afforded four mononuclear complexes, [ Ln (pztza) 2 (H 2 O) 6 ] · pztza · 3H 2 O [ Ln = Tb ( 1 ), Dy ( 2 )] and [ Ln (pmtza) 2 (H 2 O) 6 ] · Cl · 3H 2 O [ Ln = Tb ( 3 ), Dy ( 4 )]. The compounds were characterized by elemental analysis, IR spectroscopy, and single‐crystal X‐ray diffraction. X‐ray diffraction analyses reveal that all structures are mononuclear. The four compounds are self‐assembled to form three‐dimensional networks by hydrogen bonds. The different positions of the nitrogen atom control the coordination mode of the ligands and further influence the crystal structures. Furthermore, the luminescence properties were also investigated at room temperature in the solid state.
