Substituted thiourea complexes 1 complexes of some Summary A series of new Pt n and Pd I1 complexes of N,N'-disubstituted thiourea derivatives of general formulae [MLCI2]2, [MLzCI;] and [ML4]CI 2 have been prepared and characterised by physicochemical and spectroscopic methods. The reaction of these ligands with [M(DMSO)2CI2], M = Pt, cis-or Pd, trans-, in CHC13 and EtOH at ambient temperature or under reflux, is described.

New complexes of dithiocarbamate of the general formula [M(3-MeoPrdtc) 2 ] and [M(3-MeoPrdtc) 2 .nL] Where M= Fe(ΙΙ), Co(ΙΙ), Ni(ΙΙ), Cu(ΙΙ) and Zn(ΙΙ), and (3-MeoPrdtc) =3-Methoxypropyldithiocarbamate, and n=2 when L= pyridine, Isoquinoline, γ-picoline, 3,5-lutidine, n=1 when L= ethylenediamine, (1,10)-phenanthroline, have been prepared and characterized by metal analyses, infrared, conductance measurements, electronic absorption spectra and suscetptibility measurements. Magnetic moment and electronic spectra, indicate that the complexes of the type [M(3-meoprdtc) 2 ] are of tetrahedral geometry while the complexes of the type [M(3-meoprdtc) 2. nL] have octahedral geometry.

Xanthatecomplexes of the general formula [M{Ag(oleylXant) 2 } 2 ] (A) and [MM'(oleylXant) 4 ] (B) were M = Copper (II), Nickel II), Cobalt (II) M' = Cadmium(II), Zinc(II). These complexes were reacted with bidentatelewis base (1,10-phenanthroline). The result of this reaction gave the complexes [M(phen)][{Ag(oleylxant) 2 } 2 ] (I.A) and [M(phen)][M'(oleyl-xant) 4 ] (I.B), which have been prepared and measured by an infrared, magnetic suscetptibility measurements, conductance measurements, electronic spectra and elemental analysis electronic absorption spectra. These data indicate gave the result that the complexes of the type (A & B) are a square planer geometry while the complexes of the type (I.A), (I.B) have an octahedral geometry.
