ABSTRACT The title polymeric compound, [Zn(C(8)H(5)Cl(2)O(3))(2)](n), was prepared by reaction of zinc(II) chloride with 2,4-dichloro-phenoxy-acetic acid and sodium hydroxide under hydro-thermal conditions. The Zn(II) atom is coordinated in a distorted tetra-hedral environment by four O atoms from four 2,4-dichloro-phenoxy-acetate ligands. Each ligand bridges two Zn(II) atoms, forming a polymeric chain along the a axis. Adjacent chains are connected via C-H⋯Cl hydrogen bonds.

    ABSTRACT: The zinc(II) and cadmium(II) 2,4-dichlorophenoxyacetate salts were synthesized in mixed water–methanol environment and characterized by elemental analysis, IR spectrometry and thermal analysis coupled with mass spectrometry. The crystal structures were determined by X-ray crystallography (compound 1, [C18H18Cl4O8Zn]n : monoclinic, P21/c, a = 19.094, b = 7.378, c = 8.008, α = 90.00, β = 101.134, γ = 90.00, V = 1106.95; compound 2, [C16H14Cl4O8Cd]n : monoclinic, P21/c, a = 17.730, b = 7.293, c = 8.060, α = 90.00, β = 95.18, γ = 90.00, V = 1037.9). The structural and some thermal data about the presented cadmium salt were previously reported (Song et al. Acta Crystallogr E 62:m2397, 2006; Kobylecka et al. Thermochim Acta 482:49, 2009).

    ABSTRACT: The title compound, {[Zn2(CH3CO2)3(OH)(C6H7ClN2)]·C2H5OH} n , has alternating octa-hedrally and tetra-hedrally coordinated Zn(2+) ions. The octa-hedral coordination sphere is composed of one N atom of the monodentate di-amino-chloro-benzene ligand, three acetate O atoms and two bridging hydroxide ligands. The tetra-hedral coordination sphere consists of three acetate O atoms and the hydroxide ligand. The zinc ions are bridged by acetate and hydroxide ligands. The result is a laddered-chain structure parallel to [100] with ethanol solvent mol-ecules occupying the space between the chains. The di-amine ligand chlorine substitutent is disordered over two equally populated positions as a result of a crystallographically imposed inversion center between adjacent ligands. The ethanol solvent mol-ecule exhibits disorder with the two components having refined occupancies of 0.696 (11) and 0.304 (11). O-H⋯O hydrogen bonds form between the hydroxide ligand and the ethanol solvent mol-ecule. N-H⋯O and N-H⋯N hydrogen bonding between the uncoordinated amine group and the acetate ligands and the coordinated amine group are also observed.

    ABSTRACT: A new 2D zinc(II) supramolecular complex [Zn(2,4-D)(o-phen)(H2O)2](NO3) (1) (2,4-D = 2,4-dichlorophenoxyacetic acid, o-phen = 1,10-phenanthroline), was synthesized and characterized by single-crystal X-ray diffraction, elemental analyses, TG analysis, IR, and luminescence spectroscopy. For complex 1, each ZnII ion lies in a pentacoordinate distorted quadrilateral pyramidal configuration. The 8-member-ring hydrogen bonds clusters result in 1D ladder-like supramolecular chains, which further stack up by face-to-face π–π stacking interactions into 2D supramolecular layers. The TG analysis shows that complex 1 has high thermal stability. The solution and solid-state photoluminescence of 1 are reported.
