Syntheses and Structure of a Novel Layered Lanthanide–Zinc Coordination Polymer: [LaZn (HIDA)(IDA)2·0.5H2O]n

The hydrothermal reactions of La2O3, Zn(CH3COO)2·2H2O, iminodiacetic acid (H2IDA), and H2O resulted in the formation of a novel coordination polymers [LaZn(HIDA)(IDA)2·0.5H2O]n. X-ray diffraction analyses confirms that in complexe 1 La ions are lined through sharing the O atoms of IDA ligands which the octahedron-coordinated Zn ions are beside alternately to form a 1-D zigzag inorganic chain. And then a 2-D layered coordination polymer is constructed by helix bridging protonated HIDA ligands.
