The coordination polymers {[Cd( o ‐BDC‐Cl 4 )(H 2 O) 2 ]·EtOH} n ( 1 ) and {[Cd( p ‐BDC‐Cl 4 )(DMF)]·H 2 O} n ( 2 ) ( o ‐BDC‐Cl 4 = tetrachlorophthalate and p ‐BDC‐Cl 4 = tetrachloroterephthalate) were synthesized in different solvents using two isomeric tetrachlorinated benzenedicarboxylic acids. Complex 1 based on o ‐BDC‐Cl 4 features an extremely rare 2D trinodal (3,4,6)‐connected network constructed by the combination of 1D [Cd‐H 2 O] n chains and 1D [Cd 2 ( o ‐BDC‐Cl 4 ) 2 ] n loop‐like motifs. Complex 2 based on p ‐BDC‐Cl 4 has a 3D framework and shows a uninodal 4‐connected sra topology. Complexes 1 and 2 were characterized by elemental analyses, IR spectroscopy, single‐crystal X‐ray diffraction and thermogravimetric (TG) analyses. The photoluminescence of 1 and 2 were investigated in the solid state at room temperature.
