Three coordination polymers, [CdL(2,2'-bpy)] (1), [ZnL(phen)2] (2), and [ZnL(2,2'-bpy)] (3) (H2L= 2,5-dibenzoylterephthalic acid, 2,2'-bpy = 2,2'-bipyridine, and phen = 1,10-phenanthroline), were synthesized and crystallographically characterized. The compounds were further characterized by elemental analyses, FTIR, thermogravimetric analyses, and powder X-ray diffraction. Complex 1 exhibits a 2D sheet structure with (4,4) grid units, while 2 and 3 present infinite 1D zig-zag chain structures. The complexes are all extended into high-dimensional supramolecular networks through intermolecular hydrogen bonds and φ-φ stacking interactions. A structural comparison of 1-3 demonstrates that the characteristics of subsidiary ligands and slight difference in coordination models of L play a very important role in construction of the complexes. Additionally, luminescence of the complexes is also investigated at room temperature.
