The synthesis of zinc(II) and cadmium(II) 2, 4-dichlorophenoxyacetates in water-methanol environment. Structure and properties of polymeric [Zn(2,4-D) 2(MeOH) 2]n and [Cd(2,4-D) 2(H 2O) 2] n

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, [C 18H 18Cl 4O 8Zn] n: monoclinic, P2 1/c, a = 19.094, b = 7.378, c = 8.008, α = 90.00, β = 101.134, γ = 90.00, V = 1106.95; compound 2, [C 16H 14Cl 4O 8Cd] n: monoclinic, P2 1/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). © The Author(s) 2011.
