Abstract

Abstract: The coordination polymers {[Cd( o ‐BDC‐Cl4 )(H2 O)2 ]·EtOH} n (1 ) and {[Cd( p ‐BDC‐Cl4 )(DMF)]·H2 O} n (2 ) ( o ‐BDC‐Cl4 = tetrachlorophthalate and p ‐BDC‐Cl4 = tetrachloroterephthalate) were synthesized in different solvents using two isomeric tetrachlorinated benzenedicarboxylic acids. Complex1 based on o ‐BDC‐Cl4 features an extremely rare 2D trinodal (3, 4, 6)‐connected network constructed by the combination of 1D [Cd‐H2 O] n chains and 1D [Cd2 ( o ‐BDC‐Cl4 )2 ] n loop‐like motifs. Complex2 based on p ‐BDC‐Cl4 has a 3D framework and shows a uninodal 4‐connectedsra topology. Complexes1 and2 were characterized by elemental analyses, IR spectroscopy, single‐crystal X‐ray diffraction and thermogravimetric (TG) analyses. The photoluminescence of1 and2 were investigated in the solid state at room temperature. Abstract :
