Abstract Two new cadmium(II)-based materials, featuring two-dimensional (2D) [Cd-2(mu(6)-deta)(bpy)(H2O)](n) (1) and three-dimensional (3D) [Cd-2(mu(5)-deta)(bpy)(2)(H2O)](n) (2) structures, were constructed by the hydrothermal method from 2,3 ,4 ,5-diphenyl ether tetracarboxylic acid (H(4)deta) as an unexplored linker in research on coordination polymers (CPs) and 2,2 -bipyridine (bpy) as a mediator of crystallization. Microcrystalline samples of 1 and 2 were analyzed by IR/PXRD/EA/TGA and X-ray diffraction using single crystals. Structures and topologies of CPs 1 and 2 were established, revealing a 4,6L45 topological layer in 1 and a 3,5T1 topological framework in 2. Structural differences for 1 and 2 are attributed to distinct molar ratios between Cd2+ and bpy during the hydrothermal synthesis. Luminescence and thermal behavior of the obtained materials were also investigated. The present work opens up the use of an unexplored 2,3 ,4 ,5-diphenyl ether tetracarboxylic acid as a versatile and flexible linker toward the generation of functional coordination polymer materials.
