The hydrothermal reaction of the tricarboxylate ligand 5‐(carboxymethoxy)isophthalic acid (H 3 L) with Zn II , Cd II , and Sn II salts in the presence of the bisbenzoimidazole coligand 1, 3‐bis(benzimidazol‐2‐yl)‐2‐oxapropane (bbop) afforded the coordination polymers, [Zn(HL)(bbop)] n ( 1 ), [Cd(HL)(bbop)] n ( 2 ), and {[H 2 (bbop)][Sn 2 L 2 ]} n ( 3 ). The complexes were characterized by elemental analyses, IR spectroscopy, single‐crystal X‐ray diffraction analyses, thermogravimetric analyses, and fluorescence properties. The structures of complexes 1 and 2 are constructed by 1D chains and show strong blue luminescence emission. The structure of complex 3 is a 2D anionic dilayer, and shows a vase‐like porous structure occupied by the bulky [H 2 (bbop)] 2+ cation, which is an uncommon structural feature in transition metal coordination polymers. The three complexes are further connected by hydrogen bonds to form 3D supramolecular architectures.
