Abstract

Four derivatives of dithiolate (3-Chlorodithiobenzoato-3,Dithiobenzoatoperthiobenzoato nickel(II) [Ni(dtb)2S], 3-Bromodithiobenzoato-3, chloroperthiobenzoato nickel(II) [Ni(3-Cl-dtb)2S], Dithiosalicylatoperthiosalicylato, chloroperthiobenzoato nickel(II) [Ni(3-Cl-dtb)2S] Bromoperthiobenzoato nickel(II), [Ni(3-Br-dtb)2S] and nickel(II) [Ni(dts)2S] were used to synthesize various complexes with metal ions of Ni(II). The synthesis was done by reacting the appropriate aldehyde with sulfur and ammonium sulfide in THF to convert the groups of C = O and C – H in to C = S and C – S respectively. The UV.-Visible and FT-IR spectra were recorded for all complexes , the frequency of M – S bond was observed in the region of 440 – 490 cm-1 . The effect for addition of triphenylphosphine, on the complexes was studied. The nickel complexes were highly affected by triphenylphosphine. The rate and order of this reaction were determined. We found that the order of decomposition reaction is first order for all complexes with constant rate of 0.05 min-1.
