Supramolecular Coordination Assemblies Using 2-Aminodiacetic Terephthalic Acid Ligands: K[NiII(Hadta)(H2O)2]·H2O and K[Cu 1.5II (adta)(H2O)1.5]·H2O
JOURNAL OF INORGANIC AND ORGANOMETALLIC POLYMERS AND MATERIALS(2011)
摘要
Two new network structures, K[Ni-II(Hadta)(H2O)(2)]center dot H2O (1) and K[Cu (1.5) (II) (adta)(H2O)(1.5)]center dot H2O (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 counterions 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 counterions further network these 1D chain structures.
