Synthesis and characterization of new bulky binuclear palladium (II)‎ complexes

Abstract EN

Binuclear complexes [ta trachloro(tetrasubstituted phenyl thio) ethylene v di palladium (II) of general form ola [Pd2 (PET) CI4], where Pate=1,1,2,2 tetrakis (substituted phenyl thio) eth elene, have been prepared by treating Pd CI2 Or k2 PdCI4 with the ligands (Pate) in 2:1 metal to ligand molar ratios.

The substitution reactions are carried out by treating equimolar quantities of thiophinoxide (prepared from equimolar quantities of KOH and XC6H4SH in EtOH) and the binuclear complexes in order replace the chloride ions, gave a number of bulky binuclear complexes [tetra substituted phenyl thio) ethylene di palladium (II) of general form ola [Pd2(Pate)(CT)4] And [Pd2(Pate)(B T)4], where Th= thiophenol, At=0-carboxythiophenol, and B T=P -t-butyl thiophenol.

The prepared complexes were characterized on the bases of microanalysis, 1H'nmr, IR, UV-visible spectra and conductance measurements.
