Mono sodium 2,4,6-trioxotetrahydropyrimidine-1(2H)-carbodithioate (L) was prepared from barbituric acid with carbon disulfide (CS2) in the presence of sodium hydroxide, then reacted with some chloride metals to synthesis a complexes of the types [M (L) Cl (H2O)3], [M (L)2(H2O) 2] and [M(L)2] {M= Co(II), Ni(II), Cu(II)}, and [Pd (L)(H2O)2]Cl and[Pd (L)2] . These compounds were characterized using infra-red spectra FTIR, electronic spectra UV–VIS, proton nuclear magnetic resonance 1H-NMR spectroscopy, Micro Elemental Analysis, and Magnetic Measurements.These measurements indicate that the prepared complexes have octahedral, square planer or tetrahedral geometry. Molar Conductance measurements shows all the prepared complexes are non-electrolytic except the palladium complex of the type [Pd(L)(H2O)2]Cl.


Keywords: Barbituric acid, carbon disulfide, carbodithioate.
