| Abstract: | Three coordination polymers, {CdI(DBBA)]?0.5H2O}n (1, DBBA = 3,5-di(1Hbenzod]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-benzod]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. |
