Abstract
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 1 H, 13 C and 31 P NMR spectral data. Reaction of RhCl(CO)(PPh 3 ) 2 with DPEA · HCl and NaBPh 4 in methanol gave the cationic Rh(I) complex [Rh(DPEA)PPh 3 IBPh 4 but the reaction of IrCl(CO)(PPh 3 ) 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 [RhCl 3 (DPEA)] was prepared by the reaction of RhCl 3 · xH 2 O with DPEA · HCl in methanol. Reaction of PdCl 2 (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 ]Cl 2 . A novel trinuclear Pt(II) complex of the composition [Pt 3 Cl 3 (DPEA) 3 ]Cl 3 was prepared by the reaction of K 2 PtCl 4 and DPEA · HCl in water-acetone mixture. Reaction of K 2 PtCl 4 , DPEA · HCl and NH 4 PF 6 in water ethanol mixture gave the binuclear, cationic complex, [Pt 2 (DPEA) 3 ](PF 6 ) 4 . All the complexes were characterized by elemental analysis, conductivity, 1 H and 31 P NMR spectral data.
