A new 3D lanthanide compound [Pr(H2O)(C5HN2O4)(CH3COO)center dot H2O](n) (1) has been hydrothermally synthesized by employing 4,5-imidazoledicarboxylic (H3IDC) and acetic acid mixed ligands and characterized by element analysis, IR spectroscopy and thermal analysis, as well as single-crystal X-ray diffraction. The results show that complex 1 has a 3D (3,4)-connected network structure containing zigzag layers and 1D race-helical chains (P- and M-chains), which denote the first example of lanthanide coordination framework including the mixed ligands of imidazole-4,5-dicarboxlylate and acetate. Moreover, compound 1 displays a strong photoluminescent property and a high thermal stability.
