To investigate the effect of organic anions on coordination frameworks, the complexes [Cd(2, 6‐pydc)(bibix) 2 (H 2 O) 2 ] n ( 1 ) and {[Cd 4 (2, 5‐pydc) 4 (bibix) 4 (H 2 O) 4 ](H 2 O) 8 } n ( 2 ) were isolated by the reactions of 1‐{4‐[(1H‐benzoimidazol‐1‐yl)methyl]benzyl}‐1H‐benzoimidazole (bibix) and two distinct pyridyl‐dicarboxylates as organic anions with d 10 metal salts. In the resulting structures, bibix adopts different coordination modes affected by the aromatic anions, which have distinct geometric structure and bonding modes. Thus, complex 1 has a 1D chain structure, whereas complex 2 has a 2D architecture. Both complexes 1 and 2 have a strong fluorescence emission, which may be tentatively assigned to metal‐perturbed intraligand interactions.
