Abstract: | The coordination polymers (CPs), Ni(L)(H2O)4]n ( 1 ), Co(HL)2(H2O)2]n ( 2 ), {Cu(L)(H2O)3] · H2O}n ( 3 ), Mn(L)(H2O)2]n ( 4 ), Cd(L)(H2O)2]n ( 5 ), and {Zn2(L)2] · H2O}n ( 6 ), were solvothermally synthesized by employing the imidazol‐carboxyl bifunctional ligand 4‐(1H‐imidazol‐1‐yl) phthalic acid (H2L). Single‐crystal X‐ray diffraction indicated that the L2–/HL– ligands display various coordination modes with different metal ions in 1 – 6 . Complexes 1 and 2 show one‐dimensional (1D) chain structures, whereas complexes 3 – 6 show 2D layered structures. The magnetic properties of these complexes were investigated. Complexes 1 and 3 indicate weak ferromagnetic interactions, whereas complexes 2 and 4 demonstrate antiferromagnetic interactions. In addition, luminescence properties of 5 and 6 were measured and studied in detail. |
