Three coordination polymers, {[CdI(DBBA)].0.5H(2)O}(n) (1, DBBA=3,5-di(1Hbenzo[d]imidazol-1-yl)benzoate), [Cd(DBBA)(CH3COO)](n) (2) and [Cd(DBBA)(2)](n) (3), were obtained through reactions between Cd(II) salts and 3,5-di(1H-benzo[d]imidazol-1-yl)benzoic acid under different pH conditions. Compounds 1 and 2 are 3-D frameworks with rtl topology based on different binuclear Cd(II) secondary building units. Compound 3 was formed at lower pH and showed a 1-D chain assembled with M2L2 ring units. Moreover, phase purities, thermal behaviors, and photoluminescent properties have also been investigated.
