Supramolecular Coordination Assemblies Using 2-Aminodiacetic Terephthalic Acid Ligands: K[Ni~(II)(Hadta)(H_2O)_2] H_2O and K[Cu_(1.5)~(II)(adta)(H_2O__(1.5)] H_2O

摘要

Two new network structures, K[Ni~(II)(Hadta)(H_2O)_2] H_2O and K[Cu_(1.5)~(II)(adta)(H_2O__(1.5)] H_2O (2) which are stabilized by 2-aminodiacetic terephthalic acid ligands have been synthesized and structurally characterized. Supplemental analyses include infrared spectroscopy and CHN analysis. 1 contains mononuclear secondary building units that are linked through potassium counteri-ons and H-bonds to form a 3D network structure. 2 contains a 1D coordination polymer containing Cu~(II) ions with two different coordination environments. Potassium coun-terions further network these ID chain structures.
