Synthesis and characterization of new mixed ligand complexes of Zn (II) and Hg (II) with dithiocarbamate and phosphines
Complexes of the type [M (Et2DTC)2]2 [M= Zn(1) or Hg(2)] were prepared from the reaction of mercury acetate or zinc acetate with sodium diethyldithiocarbamate trihydrate (NaEt2DTC.3H2O) in (1:2) molar ratio (metal: ligand) in mixture of MeOH and H2O as a solvent. Treatment equal molar of (1) or (...

| description |
Complexes of the type [M (Et2DTC)2]2 [M= Zn(1) or Hg(2)] were prepared from the reaction of mercury acetate or zinc acetate with sodium diethyldithiocarbamate trihydrate (NaEt2DTC.3H2O) in (1:2) molar ratio (metal: ligand) in mixture of MeOH and H2O as a solvent. Treatment equal molar of (1) or (2) with diphosphine ligands {where diphos: bis (diphenylphosphino) methane (dppm), 1,2-bis (diphenylphosphino) ethane (dppe) and 1,3-Bis (diphenylphosphino) propane (dppp)} afforded complexes of the type [Zn(Et2DTC)2(dppeO)] (3); [Zn(Et2DTC)2(dpppS)] (4a); [Zn(Et2DTC)2(dppp)] (4b); [Hg(Et2DTC)2(dppm)] (6a); [Hg(Et2DTC)2(µ-dppm)]2(6b); [Hg(Et2DTC)2(dppe)](7) and [Hg(Et2DTC)2(dppp)](8), or with two moles of triphenylphosphine (PPh3) afforded a complexes of the type [M(κ1-Et2DTC)2(PPh3)2] (5a, 9a) and [M(κ2-Et2DTC)2(PPh3)2] (5b, 9b) {M= Zn, Hg}. The prepared complexes were fully characterized by different technics such as IR, NMR (1H and 31P) spectroscopy, elemental analysis, and molar conductivity. Characterization data showed that the (Et2DTC) ligand in all of the prepared complexes was coordinated with metal through the sulfur atoms of CSS- group. The geometry of the complexes (1-9) were tetrahedral around the Zn(II) and Hg(II) ions, except isomers 5b and 9b are octahedral geometry. .
