Synthesis and Spectral Study of O,O-diphenyl 2- hydroxybenzol phosphoramidothioate Ligand and Their Complexes with Some Transition Meta ions (Co+2,Ni+2,Cu+2)

Abstract

A new ligand has been synthesized: O,O-diphenyl2-hydroxybenzol phosphoramidothioate, And its complexes for some transition metals for each of (Co²⁺,Ni²⁺,Cu²⁺). Artificially ligand according to the reaction O,O-diphenyl chlorothiophosphate with salicyLamide, The complexes were synthesized in a ratio of (2: 1) metal: ligand respectively, resulted in the formation of single-core metal complexes bearing the general formula [M(L)₂]Cl₂ when (M: Co⁺²,Ni⁺²,Cu⁺²). The identity of the associated and the complexes has been determined by means of infrared spectroscopy techniques(FT-IR), ¹H-NMR, U.V.–visible, elemental analysis (CHN). And it determined some of the physical properties, The results of this study indicated that they were in agreement with the proposed synthetic formulas for these complexes
