Three position isomers 1,2‐, 1,3‐, 1,4‐phenylenediacetate and 1,4‐bis(benzimidazol‐1‐ylmethyl)benzene (bmb) were used to assembly cadmium(II) coordination polymers, [Cd(bmb)(1,2‐phda)] n ( 1 ), {Cd(bmb)(1,3‐phda)] · 0.5(bmb)} n ( 2 ), and [Cd(bmb) 0.5 (1,4‐phda)] n ( 3 ), which are characterized by elemental analyses, infrared spectra (IR), thermogravimetric analysis (TGA) and single‐crystal X‐ray diffraction. Single crystal structure analysis shows that complex 1 is a two‐dimensional wave‐like layer network. Complex 2 features a (3,5)‐connected three‐dimensional frameworks with (4 2 .6)(4 2 .6 5 .8 3 ) topology, whereas complex 3 shows a (4,4)‐connected three‐dimensional (4.6 4 .7)(4 2 .6 2 .8 2 ) topology. The structural versatility reveals that a significant structure‐directing effect of the position of the acetate groups during self‐assembly of these coordination polymers. Moreover, luminescent properties and thermal stabilities of three complexes were discussed in detail.
