| Abstract: | A mixed donor tridentate ligand bis[2-(diphenylphosphino)ethyl]amine (DPEA) was synthesized in its hydrochloride form by a modified procedure and characterized by 1H, 13C and 31P NMR spectral data. Reaction of RhCl(CO)(PPh3)2 with DPEA · HCl and NaBPh4 in methanol gave the cationic Rh(I) complex [Rh(DPEA)PPh3IBPh4 but the reaction of IrCl(CO)(PPh3)2 with DPEA · HCl in boiling benzene gave a unique complex, [Ir(H)(Cl)(CO)(DPEA)]Cl, in which five different donor atoms are coordinated to the single Ir(III) ion. A neutral, RH(III) complex of the composition [RhCl3(DPEA)] was prepared by the reaction of RhCl3 · xH2O with DPEA · HCl in methanol. Reaction of PdCl2(COD) with DPEA · HCl in benzene or methanol gave the cationic complex [PdCl(DPEA)]Cl the above reaction conducted in benzene-acetone-methanol mixture gave the 1:2 complex [Pd(DPEA)2]Cl2. A novel trinuclear Pt(II) complex of the composition [Pt3Cl3(DPEA)3]Cl3 was prepared by the reaction of K2PtCl4 and DPEA · HCl in water-acetone mixture. Reaction of K2PtCl4, DPEA · HCl and NH4PF6 in water ethanol mixture gave the binuclear, cationic complex, [Pt2(DPEA)3](PF6)4. All the complexes were characterized by elemental analysis, conductivity, 1H and 31P NMR spectral data. |
