2,3,5,6-Tetrachloroterephthalic acid (H2BDC-Cl4) has been selected for assembly with ZnII ions in the presence of the co-ligands 2,2-bipydrine (bipy) or 1,10-phenanthroline (phen). Through pH regulation, two coordination compounds were obtained at ambient temperature with the formula [Zn2(BDC-Cl4)(bipy)2(OAc)2(H2O)2] (1) and {[Zn(BDC-Cl4)(phen)2](CH3OH)(H2O)}n (2). Single-crystal X-ray analysis has indicated that complex 1 exhibits a binuclear coordination unit, while complex 2 is a wave-like polymeric chain. In both complexes, the anionic BDC-Cl4 ligands show bis-monodentate bridging coordination in the trans-mode. Because of the introduction of the bipyridyl co-ligands, multiple hydrogen-bonding interactions and p-p interactions are formed in both complexes
