“…In recent years there is observed an increasing interest on 2,4-D-H salts and coordination compounds, including salts of transition metals such as Cd(II) [12,18,19], Mn(II) [20][21][22], Zn(II) [23,24], Mg(II) [21], Ni(II) [25], Ag(I) [26], Fe(II) [27], Cu(II) [28], alkaline metals and p block elements such as Ba(II) [29], Ca(II) [30], Pb(II) [12] and lanthanides like Gd [31], Nd [32] and Eu [33]. Several mixed-ligand coordination compounds with 2, 4-dichlorophenoxyacetate (2,4-D) and other ligands (e.g.…”
