2,3,5,6-Tetrachloroterephthalic acid (H2BDC-Cl-4) has been selected for assembly with Zn-II 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 [Zn-2(BDC-Cl-4)(bipy)(2)(OAc)(2)(H2O)(2)] (1) and {[Zn(BDC-Cl-4)(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-Cl-4 ligands show bis-monodentate bridging coordination in the trans-mode. Because of the introduction of the bipyridyl co-ligands, multiple hydrogen-bonding interactions and pi-pi interactions are formed in both complexes.
